Dancing Trombone Man
Take a look at this clip from a talkshow where some guy sets out to play the trombone and suddenly bursts out into outrageous dance moves. Nobody seemed prepared for this performance, including the host (whose name escapes me).
It's also interesting to note that although the audience is predominately black, they totally dig his dance moves. When you can get the guys in the audience dancing to your antics, you know you're doing well. The ladies also seem to love him.
Oh man, what a hoot!
