- This is the first event to occur in 2000.
- A clip from "Karate Choppers" and "The Paper" were seen in the promo, despite the fact that the episodes did not air in this event.
- After the premiere of "Arrgh!" and "Rock Bottom," the narrator confuses "MuscleBob BuffPants" and "Squidward the Unfriendly Ghost" with "The Chaperone" and "Employee of the Month," even though these episodes actually premiered a week earlier.
