Patient: Where are you taking me, doctor?
Doctor: The morgue.
Patient: Hang on! I'm not dead yet!
Doctor: And we're not there yet!
Alright, listen up, buttercup. This joke is funny 'cause the doc is taking the patient to the morgue *before* they're actually dead. It's unexpected. It is a DARK joke and you are the punchline, dummy!
Neighborhood asshole
Its a quick detour, the doctor just wants the patient to see the others that died among him, before they take him to the hospital,.
