I'm on a mission to spread the word about Karl Pilkington. More people probably know about him now that the podcasts are being aired on HBO as "The Ricky Gervais Show" and "Idiot Abroad". I can't imagine anyone not finding him hilarious, any time I'm in a bad mood, I just listen to Karl Pilkington speak for a few minutes and I'll be laughing hysterically.
He's basically just a really, really stupid person who gets easily confused and says a lot of incredibly stupid things. He's sort of like a real-life version of Homer Simpson. He has his own show now, but he started out on a radio show with Ricky Gervais and Steve Merchant, the guys who made "The Office". They basically just ask him questions and then ridicule him when he says stupid things, which is every time he opens his mouth.

The third link is an entire episode, but I linked to the question and answer that is probably my favourite Karl Pilkington moment of all time. They ask him how old he is and he gets really confused.
There are hundreds of hours of radio shows, podcasts, and television shows with Karl in them, and he's never boring.
