Jimmy Fallon is classic.  He was always laughing in Saturday Night Live skits.
Yeah Jimmy Fallon is a great comedian, and a surprisingly good actor too!
I love the cowbell sketch.  That and the Debbie Downer sketch about Disney World.  They always make me laugh.
The Debbie Downer sketch is the best!!!! Especially because I felt they could always break character because of the joke. Nothing beats Stefan though.
