Patient: Doctor, every time I look in a mirror, I feel ill, as if I'm about to throw up. What's wrong with me?
Doctor: I don't know, but your eyesight is perfect.
Listen up, buttercup! The patient thinks he's sick because of what he sees in the mirror, but the doc is basically saying he's ugly. It's a burn disguised as a checkup, you walnut!
Neighborhood asshole
Good on the doctor for complementing them on their eyesight
