The only event I remember going to was a dinner party at someone's apartment.
Me and another guy (even more geeky than me, and he was quite drunk, which didn't help) were both interested in the same girl (I think she was the only pretty one there. Possibly the only female there at all).
Anyway, I won, and she ended up leaving with me to go get a drink afterwards.
A week later I discovered the geeky guy was an Internal Medicine attending. At my medical school.
And I was assigned to him for a week.
He, fortunately, either didn't remember me (he'd been pretty drunk) or was pretending not to remember me (didn't want to admit losing the girl to a med student).
