I recently found a particularly interesting blog, "Push Fluids," written by three medical interns in New York and Chicago.
Guy: Hey man, those are cool glasses.
Dr. Glasses: Mmmhmm. How much coke did you do?
G: Wha? I just complimented your glasses.
DG: Right...Thanks...and the coke?
G: Why do you think I'm on drugs?
DG: Because you look like you did a lot of cocaine.
G: ...Yeah, I did a shitload of blow.
