Joaquin Phoenix Can’t Walk A Straight Line

What happened to Joaquin Phoenix? He is personally one of my favorite actors but I couldn’t figure him out when he showed up on David Letterman.  David tried to have a good interview but Joaquin seemed a bit spaced out and non-responsive.  Shave the beard please and get back to acting.

Dumb Thoughts

Is Joaquin Phoenix putting on a show on David Letterman or do your think he mixed the wrong pharmaceuticals?  What are your thoughts on the clip?
