Joaquin Phoenix is back, and beardless

Some time ago, actor Joaquin Phoenix appeared on The Late Show with David Letterman with a beard, and acted really odd. People at the time were saying it was either that Phoenix had gone off the deep end, or it was a publicity stunt. Then, he announced he wanted to be a rapper, and there was more speculation. Finally, a documentary has come out, directed by Phoenix's brother-in-law, Casey Affleck that deals with the stars fake break-down. Now, Affleck has admitted to the whole thing being a hoax, but now, Phoenix has gone back to Letterman as an apology, and to promoted the fake movie. The video is below, but I have to wonder if there are some sour grapes, not just by Letterman, but by everyone who was either dupped, or who felt like they were lied to.

What do you think? Was this a great experiment for a season actor, or someone trying to scam you, and should be considered a lie?
