Chris Rock has branded Barack Obama a stand-up comedian's worst nightmare - because the US President is too awe-inspiring to make fun of.
Rock lampoons various public figures in his new comedy DVD special Kill the Messenger - including former White House contender John McCain and his vice-presidential running mate Sarah Palin.
But the comic insists he struggled to write jokes about the successful and charismatic Democrat, Obama.
He explains: "He's just one of those guys, you know, like Will Smith. There are no Will Smith jokes. There are no Brad Pitt jokes. You know, what are you going to say? 'You used to have sex with Jennifer Aniston. 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.
"With Obama, it's like, 'Ooh, you're young and virile and you've got a beautiful wife and kids. You're the first African-American president.' What do you say?"
Rock, who supported Obama in his campaign for the presidency, is disappointed he wasn't able to witness the 44th president as he was sworn into office yesterday. "I have to go to Sundance Film Festival. I've got a movie premier at Sundance. So I have to go to the whitest place in America - Utah." - Wenn
