Joaquin Phoenix used to be a B-class actor, but then kind of got out of the mainstream for a lil’ bit.  A few weeks ago, he appeared on The David Letterman show, acting real weird.  He proclaimed his aspiration for being a rapper and looked as if he was on the verge of beating up Letterman.  Many say it is a hoax and publicity stunt, while others say he is on drugs.

Well, recently Joaquin Phoenix performed a rap song on stage at a Miami club and, out of the blue, jumps into the crowd and starts beating up a random guy.
