Sex Is No Accident!
My first reaction to this comic is, pfsh, that's happened to me like a zillion times. But, then I thought about it: no, never with a food cart; no, I think the toilet was pointed the wrong direction; no, I don't think I've ever accidentally fucked anyplace where they had those glass guard-rails. No, they're right: I better wear condoms instead. This is from some German ad agency, info here.
