Have you heard Tracy Morgan talking to Terry Gross on Fresh Air? It is amazing. Morgan reveals himself to be not just the funniest deliverer of human language in the history of mouth-holes, but also a vulnerable madman with a broken heart and a canny understanding of his own appeal. Download it. It will blow up your brain. I have not had the pleasure of seeing Morgan live, but if he says anything half as funny as "Why you eatin' other people's french fries, pigeon? Have some self-respect! Don't you know you can fly?" then urine will surely flow freely in the streets. The good kind of urine.
