“Space Madness” is the 5th episode of Season 1 of The Ren & Stimpy Show, and aired on September 8, 1991.
Commander Höek (Ren) and Cadet Stimpy are on a mission to explore the cosmos. Commander Höek begins to display symptoms of “space madness”. Stimpy attempts to calm his sickened Officer while still maintaining his loyalty to his command, but it doesn’t last long. Close to the end of the episode, Höek asks Stimpy to guard the History Eraser button and never to touch it – otherwise, it will remove him from existence –, and, thanks to the narrator, Stimpy eventually does just that.
