Stephen Colbert Jokes John McCain 'Seems Mentally Challenged'

The guest on Tuesday's episode of "The Colbert Report" was Will Smith, who had already expressed support for Barack
Obama on "The Today Show" earlier this week. Colbert joked that perhaps he wants Obama to win so he can play him in a movie. The fake news anchor then goes on to make a tasteless joke about John McCain. Here's the partial transcript:

STEPHEN COLBERT: As an actor wouldn't it be more of a challenge to play John McCain for you. That would be a stretch.

WILL SMITH: That is a stretch. I can give that a shot.

STEPHEN COLBERT: That's Oscar territory because I don't know if you've heard him give speeches, he seems mentally challenged.

WILL SMITH: Yeah. You know how far that is from Oscar territory?
