A mullet-sporting Walken pulls a Shatner and recites Lady GaGa's song 'Poker Face' for a live studio audience. I promise not to make a 'more cowbell' joke. Poker face is actually the most viewed video on the web right now, but that's unfortunately the actual music video and not this awesome Walken rendition. Christopher Walken will always be remembered as someone who was totally original, even more so than Lady Gaga. Lady Gaga is just doing a bad Madonna impression, while Walken has a style and voice that are all his own. He can be unbelievably menacing as a bad guy, or he can be a goofy dancer and parody artist in his own right. He's amazing, babies.
