Tracy Morgan Makes Hilarious Comments While Jimmy Fallon Reads 'Twas the Night Before Christmas'

Obesity might not be funny, but Tracy Morgan and Jimmy Fallon reading Twas the Night Before Christmas is. The 30 Rock star stopped by Late Night with Jimmy Fallon on Wednesday to join the late-night host in a joint reading of the holiday classic. Well, Fallon did most of the reading while Morgan cracked jokes and added his own commentary.

I love that Fallon cracked about two-thirds of the way into the segment, further illustrating that its impossible for him to not laugh when with his former Saturday Night Live castmates. Check out the sketch for yourself after the jump.
