And Crazy Anatomy Instructor Gem #2 (in which I feel like I've stepped back into a pathophys class from the late 1800s):

CRAZY ANATOMY INSTRUCTOR (CAI): Has anyone HERE had a urinary tract infection before?

ME: Yeah.

CAI: Are you married?

ME: No.

CAI: Oh. Well, oftentimes having sex can cause them. So usually, you know, with virgins, that's not a problem.
