This episode saw "The Simpsons" surpass "The Flintstones" for the number of episodes produced for an animated series. The episode therefore deals with the issue of longevity and the problems that arise when the producers try to make a show "fresh" again. The show mainly deals with themes commonly known as "jumping the shark", instances that usually occur when a failing show adds a new character or major plot twist to boost ratings. The first theme is a commentary on adding a new character, when the show has run for too long. Usually, this is a technique used in shows that involve children who have grown up. This was the case with "Oliver" on "The Brady Bunch" and "Luke Brower" on "Growing Pains". The technique is also used in cartoons, notably with the addition of Scrappy-Doo to the "Scooby-Doo" animated series ten years after its debut. Both Poochie and Roy are used to reflect this by attempting to keep "The Itchy and Scratchy Show" and the Simpson family fresh respectively.
