TSK: Ask your doctor if rat poison is right for you
90+ grumpy old man (who has been objecting to all medical advice I’ve given so far): Ok, doc, you seem like an honest guy, so tell me the truth – isn’t my blood thinner made out of rat poison?
Cranquis: Basically, yes. When you give warfarin to rats, their blood gets too thin, and then they bleed internally and die.
Man: I KNEW IT! And you’re the first doctor to admit it when I ask. So I guess I’ll do whatever you say now.
