The Halloween '00s is the 4th of 22 chapters in The '00s. It is the first holiday-themed episode of The '00s only clocking in at number four. It takes place around Halloween 2001.
The episode starts before the first pitch of the World Series, and the Arizona Diamondbacks take on the New York Yankees just like the actual 2001 World Series. Steve and Kevin end up relying on at least one win from the Yankees in the series in order not to decide between going trick-or-treating for the first time, and potentially missing the conclusion of the Fall Classic. Meanwhile, Steve and Kevin decide to dress up as WWE wrestlers dressing up as Kane (Steve) and The Undertaker (Kevin).
