Joaquin Phoenix Bombs On David Letterman on Purpose?

Joaquin Phoenix who has said he’s quitting acting, gave what for most entertainers would be a career-ending performance on David Letterman last night. He’s supposed to be promoting his latest/last movie ‘Two Lovers’ but he gave instead an off the wall performance you’ll have to see for yourself below. Some will say he’s lost it, or on drugs, but the joke maybe on all of us, even though most are not laughing. This could all still be an Andy Kaufman routine with Casey Affleck who was reportedly back stage doing a documentary on him and his supposed foray into the music biz.
