Who does the best impression of actor Christopher Walken? Is it Oscar nominee Kevin Spacey? Or maybe comedians Kevin Pollack or Jay Mohr? Nope. It's Walken himself, as you'll see in this appearance on British television.

Walken was a guest on the London based talk show 'Friday Night With Jonathan Ross, when Ross suggested that he (Walken) show off his acting chops...with a dramatic reading of the Lady Gaga's hit song, 'Poker Face'. Needless to say, Walken does not disappoint...with his very own impersonation of Christopher Walken.
