Top Supermarket Clerk is a reality show which was Buster's favorite show after losing interest in Bionic Bunny. He had said that Bionic Bunny was just "made up stuff". It was only seen in Buster Gets Real, and mentioned briefly by Buster in Caught in the Crosswires. It is produced by Reality TV. Every week an episode airs and one of the contestant gets eliminated. Oddly the contestant that is eliminated in one episode always returns in the next one.
- Though unknown, it was probably a parody of the classic customer game show, Supermarket Sweep.
