seriously?!

Okay, this might be old news but is Joaquin Phoenix serious?! It took me about five days to actually watch his latest appearance on the Late Show with David Letterman but I'm so confused. What happened to the actor Hollywood praised and the public couldn't ignore? Who's letting this nut throw away his talent? For the sake of playing devil's advocate, let's just respect the fact that he watched his younger brother River die of a drug overdose outside the Viper Room in Los Angeles in 1993 so I suppose it's been a long time coming. Regardless of the reason, I ask please just give this clip a shot and you too will agree he's definitely on something.
