President Bush: Our intelligence tells us that when Saddam was originally killed, his soul actually went to hell. But while in hell he began a homosexual relationship with Satan, the Prince of Darkness. Satan, however, decided he didn't want to be with Hussein anymore, and broke up with him about August. When Saddam became jealous and tried to kill Satan's new lover, Chris, Satan had Saddam sent to heaven to live with Mormons as a punishment.

These events occurred in the season 4 episodes, "Do The Handicapped Go To Hell?" and "Probably."
