Colbert has a daily (well almost daily. I don't think its on on Fridays) TV show on Comedy Central (USA). Political satire and the like. Extremely funny.
Pleasantly suprised when I found the show whilst I was staying in the US a while back, because US TV is usually absolute rubbish. Colbert and John Stuart are the only real exceptions.
YouTube him up. A slight knowledge of US politics helps make it that extra bit funnier, but you'll be laughing even if you don't.
EDIT: Actually you'll be hard pressed to find clips on YouTube. I've just remembered Comedy Central, being the dickwads they are, don't like free advertising and got YouTube to take down all the clips. Judging by the fact that there are still only a handful there, seems YouTube are still taking them down.
