Joaquin Phoenix stopped by The Late Show with David Letterman last night and pretty much did his best Andy Kaufman impression. He sat there silently and would mumble an occasional answer to Dave who tried to keep the conversation going. Things turned pissy when he shot down Joaquin’s offer to perform his hip-hop music on the show who then started swearing at Paul Shaffer for laughing. I don’t want to say this is the most insane thing I’ve ever seen, but Dave would’ve been better off interviewing a homeless guy who thinks the government in his shoe. Mostly because I like my crazy non-scripted.
