The part where the hookers come up to the car had tears running down my face in the Wayne Brady sketch, but I found the Rick James sketch to be funnier.
My favourite scene from any comedy movie ever comes from There's Something About Mary. It's the speach Matt Dillon gives about how his "...Real passion is working with retards, and how they've got this one kid named Mongo.." The quotes are there to show that these are his words, not mine.
