Jack's Joke Shop

Jack's Joke Shop is a store in Elwood City that sells prank & gag items such as whoopee cushions, and fake piles of vomit. In "Buster's Sweet Success," Buster begins working there to pay the band back for the chocolate he ate that he was supposed to sell because Jack, the owner, is a longtime supporter of the school band. Buster, with his bad chocolate recipe, sells them at the store and names them Buster's Clusters. The store was originally called "Bill's Joke Shop" in earlier seasons, an example of this can be seen in How the Cookie Crumbles on a snake float during the parade.

Commercial
In Buster's Sweet Success, Buster was watching a Jack's Joke Shop commercial that went like this:

''And when you come to Jack's Joke Shop, you'll get a free sample! How about a rubber snake? An eye that's fake? Some sneezing powder? A squirting flower! Or take them all, I'm giving them away! Crazy you say? You're right it's crazy but once you try my gag's I know you'll be back for moooreeeeeee!''
