Joaquin Phoenix crazy TV antics

Joaquin Phoenix of the 'Walk the Line' fame is straaaaaaaaaangeeee!!!

He appeared on the David Letterman show in the US to promote his film, "Two Lovers," and it was like someone forced him to be there. His responses to Letterman's question were ridiculous.

Apparently, he wants to finish with acting and go into Hip Hop? I'm going to pray for him because his behaviour is highly questionable - boarding on a publicity stunt.

What's it all about?
