OLD SCHOOL!
That's what that line is from!!! When Luke Wilson is in the restaraunt with that girl and then that 16 year old chick comes up and says soemthign to him and then the girl gets up and walks out and then the Italian waiter guy says "Love, it's a motherfucker, eh?" WOOT! I'm a loser. Sorry. (and Thanks P! for the help!) This was seriously driving me bonkers.
