Funny? Funny Like how? Funny Like a clown? Does he amuse you?
Quite possibly one of the most memorable bits of dialog in all of film. It's up there with "steekin' badges" and "we need a bigger boat". And I just recently found out that Joe Pesci (playing Tommy DeVito) was friends with an actual Tommy DeVito played a real-life role in the formation of the music group, Frankie Valli and The Four Seasons.
