Steve Mazan realized his dream this week when he performed on Late Show with David Letterman. He taped his stand-up comedy set on Monday and CBS broadcast it on Friday night. This is extra special for the comedian, his friends and loved ones, because Steve Mazan had made doing Letterman his life's goal since he had been diagnosed with cancer. So here he is, on Letterman last night, with a routine about the elusiveness of hotel keys and hotel keycards. Enjoy!

NOTE: If/when CBS puts up its own clip of this on the Internets, I'll swap it in.
