Watch Bill Cosby Dancing (and Being Very Funny) on ‘Letterman’

There are few stand-up comics today who have been doing it as long as Bill Cosby. He’s 75 years old, and started doing stand-up in Greenwich Village at 25; with 50 years of performing, only Don Rickles and Joan Rivers give him a run for his money. Cos went on The Late Show with David Letterman last night, doing not only a loose and funny set, and an enjoyable panel with Dave, but busting some of his iconic (and goofy) dance moves as Paul and the band played him on to “Sweet Georgia Brown.” Check out the clip of his appearance below:
