When Halloween arrives, or what Kenny refers to as "the gay Super Bowl," he plans to go to Boystown to watch the festive costume parade. In an effort to prevent Kenny from attending, Eileen agrees to let him throw his own Halloween party at home. Eileen's tolerance is ultimately tested when Kenny recruits Stuart and his gay friends to join the big party, and he makes a BIG costume change. Meanwhile, Jimmy and Shannon plan to pull off an epic Halloween prank.
