Joaquin Phoenix's New-Found Weridness

I caught part of his interview on David Letterman last month, and now I saw this headline about him getting into an altercation with a heckler at one of his hip-hop performances.

Yeah, hip-hop. Is he on tour or something? If so, has anyone out there actually been or bought a ticket?

I'm guessing this is one big Andy Kaufman-esque thing. It does sort of sound that way, and I kind of hope it is. I think Hollywood and the media (especially all the gossip rags) need a good shaking up again.
