After decades in the biz, Steve Martin knows the drill: Be charming on a talk show to promote your new project, and, more recently, do bits that go viral the next day. But at this point, Martin has used up all his stories and ideas. On Monday night's Tonight Show, he lamented (in song, of course): "I've got plenty to promote/but I've got no anecdotes." Watch as he delivers a Broadway-worthy musical soliloquy, just when he happens to be promoting his Broadway show.
