South Park tackles the issue of hate crime by putting Cartman into juvenile hall after throwing a rock at Token. This is the prison episode of South Park, and features one of Cartman's lesser-known talents; that of being able to fit very large things up his a**.
Meanwhile, the boys are trying to find someone to take Cartman's place on the sled so they can beat the girls at a downhill sled race. They need a fat kid to make them go faster, so they pick Clyde.
Well, my synopsis aside, this episode is very good and makes a great point in the case against hate crimes.
