Letterman Has One of His Favorite Guests On … Norm McDonald [VIDEO]

I've seen almost every funny thing a person can see - and this is the funniest.

I've seen Bill Burr talk about cubicles, I've seen Patrice O'Neal talk about how gootball used to be a gladiator's sport, I've seen Robert Kelly talk about fat people at Applebee's.

Watch this.

I've had Nick Dipaolo, Rich Vos, Patrice O'Neal, Kevin Hart, Robert Kelly, Bill Burr, Aziz Ansari, Dane Cook, Andrew Dice Clay, Eddie Murphy make me laugh hysterically. I've never laughed harder at anything ... EVER.
