  Aqua Teen

  Studio Playback

  It's about time we got another yuletide rap. "Christmas in Hollis" has kind of overstayed its welcome.

  Robot Chicken

  Can't Be a Crime to Kick a Dope Rhyme

  Video games were so much gentler back then. Nobody uses a hooker as a human shield or even desecrates PaRappa's lifeless body. Wouldn't fly today.

  The Boondocks

  Eat MC's All Day

  Anyone throwing down rhymes with a tennis racket should probably be arrested on general principal anyway.

  Hesh's Wedding Rap

  Hesh wants "married sex?" Ah, single people are so charming and stupid.

  Squidbillies

  You Call That a Circus Peanut?

  You haven't really arrived until you've had a plug of snuff serenading you with a personalized rap. Even then, it's hard to say just where it is that you've arrived.

  Robot Chicken

  Dark Cristal

  Well, this version may not have a great message for kids, but it would probably cause fewer nightmares than the original.
