but... who is that guy..? o_o (sorry, I never saw him before -_-)[/quote]
He's Conan O'Brien, a famous talk show host in the US (even if he claims that he's not popular). Late Night with Conan O'Brien is the name of his show. It's pretty funny.
Funny, some of the time. Watching him too much gets you bored as he can't get too much change to the shows (but it is good considering he does it five days out of seven in a week).
