In a scene of "Hello Dolly" Samson is holding a book titled "How to Make Friends" from a shelve but on the shelve it says that it is the fishing section. (edit) The joke with an air-conditioner randomly falling out of the sky was used in the pilot of the short lived WB series Mission Hill (Ironically Tom Kenny was the voice of the guy that dropped it). (edit) Color Goof: In one shot in Hello Dolly, when we first see Dave and Ping-Pong in the bleachers, they had their normal neck color. Then, when Edward yells "QUIET!!" to the Beans in the bleachers, their neck color is the same as their beaks, and this goof is there until after Edward blows up the pickle. After the pickle blows up, they have their normal neck color. (edit) While escaping the angry mob, after the Jelly trio went into a tower, the tower's door lines are reverse. (edit) In a scene in "Hello Dolly", ten Lemmings can be seen instead of four. Moreover, other "clones" of other campers can be seen. (edit)

Hello Dolly is also the name of a famous play. (edit)
