When you are Joaquin Phoenix and you want to turn your life into a shameless cycle of self-promotion of your hate of fame - you will stop at nothing to keep your name in the headlines. First of all, you are no rapper. To think you can just get up on stage looking like the Unibomber, spit out some words and get respect is just silly. Leave that to Matisyahu. It's no surprise then, that Phoenix would stoop to gaining some street cred by attacking someone in his audience (probably a hipster who weighs all of a buck ten in a pair of skinny jeans with a Parliament Light behind his ear and a New Kids on the Block shirt).

My advice to Phoenix would be - be careful of that beard of yours. Sure you could use it to choke people (or maybe gross them out with the smell of whatever gets caught in there as you are eating) but whoever you're attacking can also use it against you!
