Asshole translates in to any language

Pompous, yuppy, 20-something guy to hispanic waiter: "Bottom's up!"
[pause as waiter admires what an ass this guy is]
Guy: "You know, that's an expression?! Like the bottom of your glass? I didn't mean anything suggestive by it!"
Waiter, in perfect English: "I know." [walks away]
