Victor Borge

Just mention his name to any pianist and see the reaction you get. Victor Borge is the King of Musical Schtick, and his sit-down comedy (at a concert grand) is legendary. This gifted Danish pianist gave "concerts" up to a ripe old age and never lost his rapier wit. He was also in demand as a guest conductor for such bands as the New York Phil. Not a bad gig for a funny guy.
Here are a few samples of his tongue-in-cheek humor:
