Hell on Earth 2006

"Hell on Earth 2006" is the eleventh episode of Season Ten of South Park.

Synopsis
Satan is throwing the world's biggest Halloween costume party, and no one is getting in without a blue wrist band. Unfortunately, even Satan can't plan for everything as a religious organization and serial killers might ruin his good time.

Plot
Satan decides that since Halloween is essentially his holiday, he is going to have a huge party — as big as a sweet sweet 16 party. He proclaims to the spirits of the damned that anyone who wants to get in must RSVP and get a blue wristband, they must wear a costume, and that not appearing will make you a loser. He also states that no one should come dressed as The Crow as that's his costume but later he makes his minion Zazul swap his Britney Spears costume with him, yelling "No one can look hotter than me!" He also invites many celebrities, and plots to have it become the greatest party ever by ordering a cake the size and shape of a Ferrari, which three notorious serial killers — Ted Bundy, Jeffrey Dahmer, and John Wayne Gacy — are ordered to bring. Meanwhile, the Roman Catholic Church, angered that Satan doesn't invite them to the party, plans to call the fire marshal the night of the party to complain, thus ruining it.

The South Park boys experiment with a Bloody Mary-type ritual to summon Biggie Smalls and Butters succeeds in summoning him. However, Biggie already has a blue wristband and, since he is on Earth and cannot use the inter dimensional vortex opened from Hell to get to the party, demands that Butters help him get to the party.

Finding out that Butters disappeared, the kids decide to try to see if the Biggie Smalls thing really works, and do the mirror trick again; Smalls, who was sitting next to Butters on a plane bound for Los Angeles where the party is located, teleports against his will to South Park again, and in a rage starts shooting at the boys because he is held up from attending the party once again. (He is later summoned against his will, once again, by Randy, Stan's dad.) The Catholic Church tries to call the fire marshal, but to their shock, they find that Satan has cleverly invited him — so they decide to crash the party. However, Satan's Security makes sure they don't get in at all.

The three serial killers, in typical Three Stooges fashion, run into trouble trying to pick up the cake: having killed the bakers. This is compounded as every time they enlist someone's help, Gacy (and once Dahmer) kills them and Dahmer performs necrophilia and cannibalism on the body. Ted Bundy's attempts to discipline them only slows progress down further. When an attempt to lift the cake fails, resulting in its destruction, the killers know they're in trouble. When trying to bake a new one, the three mutilate each other to the point where they cannot bake it, and Satan's minions wind up getting an Acura cake as a last minute substitute.

Satan flies into a rage over the Acura cake, screaming that the party is about him despite everyone having fun. The partygoers get upset, and Satan realizes that he has become like one of the girls on MTV. He tells the crowd that he is sorry and that his party is for all of the people who make his life so special ("And if I don't realize that, then I'm no better than a rich American teenage girl"). Now he wants everyone to enjoy his party so he invites everyone in. Butters makes it to the party and uses a makeup mirror to summon Biggie Smalls straight to the party, who invites Butters into the party as thanks. The episode ends with everyone dancing, including a group of Catholic priests with naked boys on leashes.

Controversy
The episode sparked controversy shortly after it was aired due to the Steve Irwin parodies it contained, and was panned by critics and Irwin's family. Despite the controversy, the episode received fairly high review ratings, as well as being favored among user-rated websites.
