Maybe I'm just such a guy, but I love blooper and practical joke shows. When actors screw up and live news reports go horribly wrong. That's why I laughed so much at this clip from last night's Late Show with David Letterman. It's not the lame hidden camera jokes that Biff Henderson tries to play on people, it's that he can't get the name of the segment right. I find that funny (Biff is always funny anyway).
