my favorite "overheard" of the day:

Guy #1: Dude, I think I'm finally starting to sober up.
Guy #2: How can you tell?
Guy #1: Because all of a sudden I can do square roots in my head again.

--Dorm elevator, Columbia University

all the time I overhear conversations, especially at my wacky library job, which are so hilarious and I consider submitting them. 99% of them are "you had to have been there" kind of jokes. which, if you weren't there, just aren't funny.
oh well.
