Joaquin Phoenix High as a Kite on Letterman

Did you see Joaquin Phoenix on David Letterman on February 11, 2009? I hope that Joaquin Phoenix is pulling our leg, otherwise he's going to overdose on something or other any minute now.

Not only was Joaquin Phoenix incredibly disrespectful by chewing gum, he acted like he had no idea what was going on. But as always, David Letterman managed to turn the whole thing into a joke and had the audience in stitches.

It's quite possible that Joaquin Phoenix is trying out some kind of weird experiment on us and David Letterman wasn't in on it, or it would ruin the eventual release on something great. That, or we're about to see the full on demise of a great actor turned rapper. He was there to promote his last movie Two Lovers, but it turned into a massive joke. And the beard and sunglasses just put the whole situation into overdrive.

The best part? When David Letterman says, "Joaquin, I'm sorry you couldn't be here tonight."
