Chris Rock on Obama: "There's nothing to say about Brad Pitt"

...thanks to the Internet, the world is a lot smaller than it was even 10 years ago. And people are digging the same jokes, he said, including ones about John McCain and Sarah Palin.

As the DVD readies for release on January 20, CNN talked with Rock about his lack of Obama jokes, Inauguration Day and why racism will never die. The following is an edited version of that interview:

CNN: I watched the special last night, and I noticed that you did a lot of jokes about John McCain -- his age, his war hero story -- but not so many about Barack Obama. Is it harder to make fun of Obama?

Chris Rock: He's just one of those guys, you know, like Will Smith. There's no Will Smith jokes. There's no Brad Pitt jokes. You know, what are you going to say? "Ooh, you used to have sex with Jennifer Anniston. Now you have sex with Angelina Jolie. You're such a loser." What do you say? "Ooh, your movies are big. You make $20 million." There's nothing to say about Brad Pitt.
