As it was with William Shatner reading Sarah Palin's resignation speech, so it is with this: it's all in the delivery.
On a UK talk show hosted by Jonathan Ross, the wacky and wonderful Christopher Walken gave a spoken-word rendition of pop sensation Lady Gaga's hit song "Poker Face." And, because it's Walken, it's genius. There's something in the way that he throws himself into it totally - and yet realizes that doing this makes it ridiculous - that elevates this to art.
Strangely, Ross seems to have a history of getting Walken to put his vocal talents to good use as here, from circa 1993, is the actor reading The Three Little Pigs.
