- During the tour of the Duff Brewery, the three vats are marked "Duff", "Duff Light", "Duff Dry". The vats are filled by the same pipe, indicating different names for exactly the same product. This may be reference to a urban legend that some gas stations hooked up their regular, plus, and super unleaded to the same tank, charging more money for customers who bought plus or super while getting the same product.
- In the syndicated version both Martin Prince, Jr. and Nelson Muntz's exhibits at the Science Fair were removed. Martin had a flying balloon which was deflated from a B.B. Gun shot by Nelson from his B.B. Gun exhibit, which he states that he was aiming for Martin's head. In the DVD release, this scene was left in uncut.
- In a scene at Moe's Tavern there are two Larrys.
