The system did not break. It is working exactly as designed.

Four of them. The second one should not be legal.

SEND this to whoever fights this queue with you.

Email: "Exciting news — our practice has joined a new partner network."
Me: "Who owns us now?"
Admin: "A fund."
Me: "A fund owns the room where I decide whether someone gets a clot-busting drug in the next twenty minutes?"
Admin: "The fund is very excited about your throughput."

Me: "I need a Spanish interpreter."
Clinic: "The tablet is on cart four."
Me: "Cart four is in the other building."
Clinic: "Then use the family member."
Me: "The family member is the person I am here to ask about."

Records: "We cannot accept the outside MRI electronically."
Me: "How should it arrive?"
Records: "On a disc."
Me: "My computer has not had a disc drive since 2016."
Records: "Then bring it to the third floor."

Case manager: "He does not meet inpatient criteria."
Me: "He cannot walk."
Case manager: "Since when?"
Me: "Since yesterday. That is the reason he is here."
Case manager: "Is it expected to last two midnights?"
Me: "I am a neurologist, not a fortune teller. And also yes."

Explained: (1) Intravenous thrombolysis for acute ischaemic stroke is a time-critical physician decision: the probability of a good outcome falls with every minute of delay from symptom onset to treatment, which is why door-to-needle time is a tracked quality measure. (2) Using family members as ad hoc interpreters is discouraged because it introduces omission and error; in a cognitive evaluation the accompanying relative is also the informant, so the roles are in direct conflict. (3) Image exchange between unaffiliated health systems still frequently depends on physical CD-ROM transfer despite the existence of electronic image-sharing standards, causing repeat imaging and delay. (4) Under the Medicare two-midnight rule, inpatient admission status turns on the physician's expectation that medically necessary care will span two midnights, which requires a prospective prediction about an unpredictable course.

Send this to the colleague who found out who owns their practice from an email.

Explained: Intravenous thrombolysis for acute ischaemic stroke is a time-critical physician decision: the probability of a good outcome falls with every minute of delay from symptom onset to treatment, which is why door-to-needle time is a tracked quality measure.

Admin: "Your patient satisfaction score dropped.

Watch the reel

Admin: "Your patient satisfaction score dropped."
Me: "I told four families bad news that week."

Four of these. All of them real.

SEND this to whoever fights this queue with you.

Admin: "Your patient satisfaction score dropped."
Me: "I told four families bad news that week."
Admin: "The survey doesn't have a field for that."
Me: "I know. I looked."
The satisfaction score. There is no box for the week you spent saying the hardest sentences in medicine.

Insurance: "Denied."
Me: "It costs four dollars."
Insurance: "Denied for four dollars."
Me: "You spent more than that denying it."
Prior auth on a generic. Somewhere there is a spreadsheet where the review costs more than the medication, and the spreadsheet has been approved by four people.

Scheduler: "The next new-patient slot is May."
Me: "May of what?"
Scheduler: "...I was hoping you would not ask."
New-patient neurology access. The answer to a scheduling question should not require a follow-up question about which calendar year.

Payer: "We're clawing back a visit from 2024."
Me: "On what grounds?"
Payer: "Documentation didn't support the level of service."
Me: "She had a stroke."
Payer: "We'd need that documented."
Me: "It's the first word."
The retrospective audit. Two years later, a letter arrives to explain that the emergency was insufficiently described.

Explained: (1) No clinical claim. Satirizes patient-experience survey instruments as a performance metric; makes no assertion about any patient, family, or real survey result. (2) No clinical claim - satire of utilization review economics. Names no drug, no patient, no payer. (3) No clinical claim. Long wait times for new outpatient neurology appointments are widely documented; the card asserts no specific national figure. (4) No clinical claim about stroke care. Satirizes retrospective payer audits and documentation-based recoupment; makes no assertion about coding rules or any real audit.

School nurse: "The seizure action plan needs a wet signature and a fax number.

Sun, 13 Sep 2026 16:00:00 +0000

School nurse: "The seizure action plan needs a wet signature and a fax number."
Me: "A fax number."
Nurse: "For the safety of the children."
Me: "The children have phones. The plan does not."

Back-to-school paperwork. Every August, a document designed to keep a kid safe in a classroom gets routed through a technology that peaked during the first Bush administration.

Send this to whoever owns the fax machine.

Explained: No clinical claim - satire of school health documentation workflow. A written seizure action plan is a real, standard school document; the card makes no claim about its content.

IT: "The ambient AI writes your note now — you just sign it.

Sun, 13 Sep 2026 16:00:00 +0000

IT: "The ambient AI writes your note now — you just sign it."
Me: "It turned 'no purposeful movement' into 'resting comfortably.' I am not signing that."

Send this to whoever volunteered your unit for the AI pilot.

Explained: Ambient AI scribes are documented to soften or alter clinical language in generated notes, which the physician must catch and correct before signing.

Me: "March of what?"
PCP: "I was hoping you'd know."
Specialty access. Two doctors staring at the same calendar, neither of whom controls it.

EMR: "Please document tobacco use."
Me: "He is four days old."
EMR: "Please document tobacco use."
Me: "Never. He has never smoked. It has been a very clean four days."
The required field that does not care who the patient is. You will answer it. You will answer it about a newborn.

Explained: (1) Ambient AI scribes are documented to soften or alter clinical language in generated notes, which the physician must catch and correct before signing. (2) No clinical claim - satire of school health documentation workflow. A written seizure action plan is a real, standard school document; the card makes no claim about its content. (3) No clinical claim. Access-to-care satire about specialty referral wait times; makes no assertion about headache diagnosis or management. (4) No clinical claim. Satirizes mandatory EHR screening fields that fire regardless of patient age. Makes no assertion about neonatal care, tobacco, or any real patient.

Is there a doctor on board?

Sat, 12 Sep 2026 16:00:00 +0000

"Is there a doctor on board?"
Me, standing up: "I'm a neurologist."
Flight attendant, still scanning the cabin: "...anyone else?"

Send this to the specialist who'd be exactly as useless at 35,000 feet.

Explained: No medical claim — self-deprecating joke about neurology's limited usefulness in an acute in-flight emergency. Punches at ourselves.

Me: "The AI note says the patient denied recent travel.

Sat, 12 Sep 2026 16:00:00 +0000

Me: "The AI note says the patient denied recent travel."
Resident: "He's been intubated since Tuesday."
Me: "So it interviewed him spiritually."

Send this to the resident who catches the AI's inventions before you do.

Explained: Ambient AI scribes are documented to fabricate plausible-sounding clinical details that were never said, which the signing physician must catch.

Vet: "It's idiopathic vestibular disease. He'll be steady again in two weeks.

Wed, 02 Sep 2026 16:00:00 +0000

Vet: "It's idiopathic vestibular disease. He'll be steady again in two weeks."
Me: "Which way does the fast phase beat?"
Vet: "...The what."
Me: "The nystagmus. I need to know if it's peripheral."
Vet: "Sir. It is a dog."

My dog has a head tilt and I have a differential. Neither of us is enjoying this.

Send this to the colleague who cannot turn it off around their own pets.

Explained: Idiopathic (old-dog) vestibular disease is a common, self-limited canine condition causing acute head tilt, nystagmus and ataxia. In human vestibular assessment, the direction and behavior of nystagmus is one of the features used to separate peripheral from central causes.

Family, watching a hospital show: "Is any of this real?

Tue, 01 Sep 2026 16:00:00 +0000

Family, watching a hospital show: "Is any of this real?"
Me: "Some of it."
Family: "Which part is wrong?"
Me: "He called it a stroke from the doorway."
Family: "He could see her face."
Me: "So could I. Faces are the easy half."

Face-arm-speech screens are built to be fast and sensitive, not to be a diagnosis. They are tuned to the front of the brain's blood supply, which is why posterior-circulation strokes — the ones that arrive as sudden vertigo, double vision, a lost half of the visual world, or a person who simply cannot walk straight — are the ones most often missed at the door. The face is the easy half. Send this to whoever quotes a TV doctor at you.

Send this to whoever quotes a TV doctor at you.

Explained: Prehospital stroke screens such as FAST and the Cincinnati Prehospital Stroke Scale are designed as sensitive triage tools rather than diagnostic tests, and they systematically under-detect posterior-circulation stroke, which more often presents with vertigo, diplopia, visual field loss, or gait ataxia than with facial droop.

Credentialing: "We need your medical school diploma.

Tue, 01 Sep 2026 16:00:00 +0000

Credentialing: "We need your medical school diploma."
Me: "You have had it since March."
Credentialing: "We need a color copy."
Me: "It is a diploma. It is beige."
Credentialing: "In color."

Credentialing has my diploma. Credentialing would like my diploma, in color.

Send this to anyone who has ever been credentialed at a second hospital.

Explained: No clinical claim. Describes hospital credentialing/primary-source verification paperwork.

Why does the second hand seem to freeze the moment you glance at a clock?

Sat, 29 Aug 2026 16:00:00 +0000

Why does the second hand seem to freeze the moment you glance at a clock?

Because your brain hides the blur of a fast eye movement, then backfills the gap with whatever you land on — so that first second gets stretched.

The clock is fine.

You are editing the tape and you were never told.

Glance at a clock and the first second looks too long. That is not the clock. That is your brain retroactively filling in the time it deleted while your eyes were moving.

Save this and try it on the nearest analog clock.

Explained: Chronostasis (the 'stopped clock illusion'): following a saccadic eye movement, the perceived duration of the first fixation is overestimated, because the visual system backdates the post-saccadic image to cover the period of saccadic suppression. Well-described perceptual phenomenon.

Survey: "This is completely anonymous.

Fri, 28 Aug 2026 16:00:00 +0000

Survey: "This is completely anonymous."
Survey: "Department?"
Survey: "Role?"
Survey: "Years in practice?"
Me: "There are two of us."

The anonymous wellness survey would like three identifying details, purely for context.

Send this to your department before they fill it out.

Explained: No clinical claim. Describes the common design flaw of workplace 'anonymous' surveys that collect enough demographic fields to identify small departments.

Student: "Why does the nerve to the voice box dive down into the chest and loop back up?

Wed, 26 Aug 2026 16:00:00 +0000

Student: "Why does the nerve to the voice box dive down into the chest and loop back up?"
Me: "Because a fish needed it there four hundred million years ago and nobody ever filed the change request."

The recurrent laryngeal nerve. The single most famous piece of bad routing in the human body, and it is bad routing for a reason.

Send this to whoever told you the body was well engineered.

Explained: The recurrent laryngeal nerve does not travel directly to the larynx: it descends into the thorax and loops back up — under the aortic arch on the left, under the subclavian artery on the right. This detour is the standard evolutionary-developmental explanation, reflecting the descent of the great vessels from the ancestral branchial arch arrangement seen in fish.

The weakness starts in the toes and climbs — legs, then trunk, then hands. Guillain-Barré is the one disease polite enough to announce which floor it's on.

Fri, 21 Aug 2026 16:00:00 +0000

The weakness starts in the toes and climbs — legs, then trunk, then hands. Guillain-Barré is the one disease polite enough to announce which floor it's on.

The reflexes disappear on the way up.

Send this to the resident who calls every ascending weakness 'probably nothing.'

Explained: Guillain-Barré syndrome (acute inflammatory demyelinating polyradiculoneuropathy) classically causes ascending, symmetric weakness with hyporeflexia/areflexia.

Your two brain halves cooperate only because of one 200-million-fiber cable. Sever it and each hemisphere runs its own agenda — same skull, two minds that stop telling each other anything.

Thu, 20 Aug 2026 16:00:00 +0000

Your two brain halves cooperate only because of one 200-million-fiber cable. Sever it and each hemisphere runs its own agenda — same skull, two minds that stop telling each other anything.

Send this to the person whose left hand never knows what the right is doing.

Explained: The corpus callosum is a commissure of roughly 200 million axons connecting the cerebral hemispheres; when it is cut (callosotomy / classic split-brain studies) each hemisphere can process independently and inter-hemispheric transfer is lost.

Off a cruise and the floor still rocks for days? Mal de débarquement — your brain learned the boat so well it refuses to unlearn it. Loyalty, basically.

Wed, 19 Aug 2026 16:00:00 +0000

Off a cruise and the floor still rocks for days? Mal de débarquement — your brain learned the boat so well it refuses to unlearn it. Loyalty, basically.

Send to whoever's still on the boat.

Explained: Mal de débarquement syndrome is a persistent perception of self-motion (rocking/swaying) after passive motion exposure (cruises, flights), attributed to maladaptive persistence of vestibular adaptation.

Why does a song get stuck in your head? An 'earworm' is your auditory cortex looping a catchy fragment — usually one it never got to finish. Your brain hates a cliffhanger.

Tue, 18 Aug 2026 16:00:00 +0000

Why does a song get stuck in your head? An 'earworm' is your auditory cortex looping a catchy fragment — usually one it never got to finish. Your brain hates a cliffhanger.

Tag whoever just started humming.

Explained: Involuntary musical imagery ('earworms') involves the auditory cortex and phonological loop; unresolved/uncompleted tunes are more likely to recur (a Zeigarnik-like effect).

Lose enough hearing and the brain, refusing the silence, starts scoring your empty apartment with big-band music only you can hear.

Mon, 17 Aug 2026 16:00:00 +0000

Lose enough hearing and the brain, refusing the silence, starts scoring your empty apartment with big-band music only you can hear.

Send to the brain-nerd who'll love this one.

Explained: Musical ear syndrome (auditory Charles Bonnet): musical hallucinations arising with acquired hearing loss.

A neurologist wearing a stethoscope is wearing jewelry. I brought a reflex hammer, a tuning fork, and a safety pin. The stethoscope is here for the photo.

A neurologist wearing a stethoscope is wearing jewelry. I brought a reflex hammer, a tuning fork, and a safety pin. The stethoscope is here for the photo.

send to the neurologist who never uses their stethoscope

Explained: No strong clinical claim — a neurologist’s exam leans on the reflex hammer, tuning fork, and pinprick more than auscultation; in-group specialty humor.

The outside hospital sent your 'STAT' transfer imaging on a CD. A physical CD. In this economy.

Sat, 15 Aug 2026 16:00:00 +0000

The outside hospital sent your 'STAT' transfer imaging on a CD. A physical CD. In this economy.

I found a laptop old enough to have a disc drive. The clot did not wait for the loading bar.

send to anyone who's fought a hospital CD drive at 3am

Explained: Trivial/system: outside-facility imaging is often transferred on physical CDs, and acute stroke imaging is time-critical (delays reduce salvageable tissue). No non-trivial clinical claim.

A TIA is a stroke that changed its mind

Sat, 15 Aug 2026 16:00:00 +0000

A TIA is a stroke that changed its mind

Same warning shot

It just skipped the ending.

Save this the next time someone calls a TIA a 'mini' anything.

Explained: A transient ischemic attack (TIA) produces stroke-like symptoms that resolve without permanent infarct, but marks a significantly elevated short-term risk of a subsequent stroke — a warning sign, not a benign event. (Descriptive, not advice.)

In any other job, a concussion is a medical event. In football it's a depth-chart problem — 'next man up,' like a frontal lobe is a backup left tackle. You cannot sub in a spare brain from the bench. There's exactly one, and it doesn't come off IR in a week.

Fri, 14 Aug 2026 16:00:00 +0000

In any other job, a concussion is a medical event. In football it's a depth-chart problem — 'next man up,' like a frontal lobe is a backup left tackle. You cannot sub in a spare brain from the bench. There's exactly one, and it doesn't come off IR in a week.

Send this to the group chat that treats brains like roster depth.

Explained: The brain is not a rapidly replaceable or interchangeable body part; concussion recovery is individualized and not governed by roster/return-to-play timelines. Culture-and-system satire; no injured athlete is targeted.

Nurse: “he's a fall risk, I put the yellow socks on.” Me: “the whole floor is a fall risk — it's a sea of yellow socks.” The intervention is a color. Gravity remains undefeated.

Thu, 13 Aug 2026 16:00:00 +0000

Nurse: “he's a fall risk, I put the yellow socks on.” Me: “the whole floor is a fall risk — it's a sea of yellow socks.” The intervention is a color. Gravity remains undefeated.

send to anyone who's drowned in a floor full of yellow socks

Explained: Satire of fall-risk color-coding as a checkbox intervention; no clinical claim about any patient.

Chili isn't hot. It picks the lock on your heat-and-pain receptor, TRPV1, and your brain files a burn report for a fire that isn't there.

Thu, 13 Aug 2026 16:00:00 +0000

Chili isn't hot. It picks the lock on your heat-and-pain receptor, TRPV1, and your brain files a burn report for a fire that isn't there.

You're being catfished by a pepper.

Send this to the person who swears they 'love the pain.'

Explained: Capsaicin activates the TRPV1 receptor (which also responds to noxious heat >~43°C), producing a burning sensation without any actual temperature change.

My coffee has a coffee. The second one exists purely to resuscitate the first one after the morning it just had.

Tue, 11 Aug 2026 16:00:00 +0000

My coffee has a coffee. The second one exists purely to resuscitate the first one after the morning it just had.

send to your fellow two-coffee-minimum human

Explained: Clinician-life caffeine gag; no medical claim.

Insurance approved the drug — just not that one, or that dose, or for this diagnosis, or in this decade. The formulary is a menu where everything good is quietly marked 'market price.'

Sun, 09 Aug 2026 16:00:00 +0000

Insurance approved the drug — just not that one, or that dose, or for this diagnosis, or in this decade. The formulary is a menu where everything good is quietly marked 'market price.'

send this to anyone who's fought a formulary

Explained: Restrictive formularies and step-therapy limit which drugs/doses clinicians can prescribe; this satirizes the administrative system, not patients.

“Walk heel-to-toe like a sobriety test.” It IS the sobriety test — same midline cerebellum the beer was insulting. That roadside cop was running a neuro exam and had no idea.

Sun, 09 Aug 2026 16:00:00 +0000

“Walk heel-to-toe like a sobriety test.” It IS the sobriety test — same midline cerebellum the beer was insulting. That roadside cop was running a neuro exam and had no idea.

send this to the friend who 'aced' their sobriety test

Explained: Tandem (heel-to-toe) gait tests midline cerebellar (vermis) function; roadside field-sobriety tests probe the same circuitry.

A sideline 'concussion check' that takes 90 seconds and ends in a thumbs-up is a vibe check, not a neuro exam. The brain didn't agree to your broadcast schedule.

Fri, 07 Aug 2026 16:00:00 +0000

A sideline 'concussion check' that takes 90 seconds and ends in a thumbs-up is a vibe check, not a neuro exam. The brain didn't agree to your broadcast schedule.

Send this to whoever yells 'he's fine, put him back in.'

Explained: A thorough sideline concussion assessment (e.g., SCAT-style graded exams) takes meaningful time; an ultra-brief check is inadequate to rule out concussion. Framed as culture/protocol satire, not about any athlete.

The smallest muscle in your body lives inside your ear, and a split second before you speak it braces and turns your own voice down so you don't deafen yourself from the inside. Your body mutes you before you say a word. Some of us could use that upgrade elsewhere.

Thu, 06 Aug 2026 16:00:00 +0000

The smallest muscle in your body lives inside your ear, and a split second before you speak it braces and turns your own voice down so you don't deafen yourself from the inside. Your body mutes you before you say a word. Some of us could use that upgrade elsewhere.

Send this to the loudest person in your group chat (lovingly).

Explained: The stapedius (smallest skeletal muscle) contracts as part of the acoustic/attenuation reflex, including around vocalization, dampening loud and self-generated sound to help protect the inner ear.

Look at your own eyes in a mirror and flick them side to side. You will never catch them moving. Your brain switches vision off for a few milliseconds during each jump and stitches the gap so smoothly that you're briefly blind a fraction of every second — and never once notice.

Tue, 04 Aug 2026 16:00:00 +0000

Look at your own eyes in a mirror and flick them side to side. You will never catch them moving. Your brain switches vision off for a few milliseconds during each jump and stitches the gap so smoothly that you're briefly blind a fraction of every second — and never once notice.

Send this and watch your friend try it in the mirror for ten minutes.

Explained: Saccadic masking/suppression: visual perception is suppressed during rapid eye movements (saccades), which is why you cannot observe your own saccades in a mirror even though others can see them.

'He's a warrior, he played through it.' Cool. The brain does not have a warrior mode. It has a swelling mode.

Thu, 30 Jul 2026 16:00:00 +0000

'He's a warrior, he played through it.' Cool. The brain does not have a warrior mode. It has a swelling mode.

Send this to anyone who says 'shake it off' about a head hit.

Explained: Head injury triggers a metabolic/inflammatory cascade (and can cause cerebral edema); 'toughing out' a head impact is a cultural narrative, not a neurological capability. Satire targets the 'warrior' culture and commentary, never the injured athlete.

You asked one question. The MRI answered with three things nobody was looking for, each needing its own scan. This is how imaging quietly funds its own future.

Wed, 29 Jul 2026 16:00:00 +0000

You asked one question. The MRI answered with three things nobody was looking for, each needing its own scan. This is how imaging quietly funds its own future.

send to the radiologist who lives in the reading room

Explained: Incidental findings ('incidentalomas') are common on brain MRI and frequently trigger additional imaging or follow-up; dry satire, not a claim about any specific case.

'Muscle memory' isn't in the muscle at all. Ten thousand reps live in your cerebellum and basal ganglia, running the play so your thinking brain gets to sit the bench.

Tue, 28 Jul 2026 16:00:00 +0000

'Muscle memory' isn't in the muscle at all. Ten thousand reps live in your cerebellum and basal ganglia, running the play so your thinking brain gets to sit the bench.

save this and send it to the gym bro

Explained: Procedural (motor) learning — 'muscle memory' — is encoded by the cerebellum, basal ganglia, and motor cortex, not by muscle tissue itself.

A brain shunt is just indoor plumbing for spinal fluid — and like all plumbing, it clogs at 2 a.m. on a holiday weekend, never on a quiet Tuesday.

Mon, 27 Jul 2026 16:00:00 +0000

A brain shunt is just indoor plumbing for spinal fluid — and like all plumbing, it clogs at 2 a.m. on a holiday weekend, never on a quiet Tuesday.

tag the neurosurgeon whose pager knows the holiday schedule

Explained: CSF shunts (e.g., ventriculoperitoneal shunts for hydrocephalus) are prone to mechanical obstruction/failure over time and are a leading reason for revision surgery.

There's a clump of about 20,000 neurons just above your eyes running a clock you cannot turn off.

Thu, 23 Jul 2026 16:00:00 +0000

There's a clump of about 20,000 neurons just above your eyes running a clock you cannot turn off.

The suprachiasmatic nucleus. Jet lag is just those cells refusing to accept your travel plans.

Save this for the next time someone brags they 'don't really need sleep.'

Explained: The suprachiasmatic nucleus (SCN) of the hypothalamus, sitting just above the optic chiasm and containing roughly 20,000 neurons, is the body's master circadian pacemaker. It is entrained to the light-dark cycle via direct input from the retina and governs sleep-wake and other daily rhythms; jet lag reflects the lag between the SCN's rhythm and a new time zone.

Broken Q-tip...

Tue, 21 Jul 2026 16:00:00 +0000

Broken Q-tip...
Reflex hammer...
EEG...
MRI...
My most advanced diagnostic tool is still asking 'and then what happened?'

Send this to the resident ordering the fifth MRI instead of asking one more question.

Explained: Trivial: history-taking remains a primary diagnostic instrument in neurology — no specific claim to verify.
