Space Madness/The Boy Who Cried Rat!

On their journey through space, Ren and Stimpy find that the true danger is "Space Madness", a cabin-crazy condition that Ren succumbs to. Next, in a sick tribute to classic animation, the two cook up a ploy to act as a rodent removal service. Ren becomes the mouse, and Stimpy as the cat. They take their services to suburbia with mixed results. (imdb)
