Why are you laughing at Joaquin Phoenix?

Last night on David Letterman, people got the chance to see how far Joaquin Phoenix would take his Andy Kaufman routine. The answer: pretty far. Letterman spent the entire night ripping into Joaquin while he just sat there mostly silent and acting high. The whole thing was rather bizarre and a could be considered a disaster by some. Letterman could have interviewed a pedophile about what he did to his victims and it’d be less uncomfortable.
