Robot Chicken is cartoon that airs on the Cartoon Network as part of the Adult Swim  lineup of programming.  THIS CARTOON IS NOT FOR CHILDREN. If you're kids are watching it stop them!!  If you know somebody who is letting their children watch this, beat them and their kids!! There is no ambiguity about this programs audience.  Yes it's animated but the subject matter is strictly adult.  Robot Chicken parodies primarily cartoons but celebrities, politicians or anything news worthy is fair game.  If you are easily offended stay away from this show.  If you want to see politically incorrect spins in Star Wars, Rainbow Brite, Thunder Cats, President Bush and whatever else the creators decided to rip apart this is the cartoon for you.  Check out clip below, you will never think about Gummy Bears the same way again.  You will laugh more each time watch it.  This is one of those clips that everybody at work will gather around your desk to watch, then forward it to everyone they know.  If you don't laugh, somethings wrong with YOU!

Wikipedia has a great Robot Chicken  web page with background information about the show.
