Brooks Sousaphone

Brooks Sousaphone is an actor in American Whoopee whose character is unknown. We only see him appear during the finale montage of the trailer. He is wearing socks and a long white shirt when he slides into frame. When he spins around, we see he is holding a racket as a makeshift microphone. He sings his heart out while shimming back and forth, then the scene changes.

This bit that Brooks does is in reference to the movie Risky Business.
