Weird Science - Season 4 - Eps 10: Chett World
Mr. Donnelly gives Chett the boot and kicks him out of the house until he can find a job. Unfortunately for Chett, there's nothing that he's qualified to do. Wyatt asks Lisa to zap up ""A Man's Man's World"" and creates a monster truck-cigar-jerky-paintball store, since those are the only thing that Chett's any good at. Chett gets a job at the store, working for Mickey and Rhett, who strangely resemble rats. In fact, they are rats. Lisa accidentally turned Rhett and Mickey, two alley rats, into humans. The bad news is that the rats plan to wipe out the human race by using the plot from Invasion of the Body Snatchers. Chett, not really realizing what's going on, aids them in their quest.
