Stimpy's Invention

Plot

In a rare display of heightened intellect, Stimpy builds a string of useless gadgets and forces Ren to test them. The Cheese-O-Phone accomplishes nothing, and the Remote Controlled Shaver glitches, stripping Ren of his fur. Ren initially likes the Stay-Put Socks, which are filled with glue, but they lock his feet in place, driving him to frustration. Mistaking Ren's anger for sadness, Stimpy vows to craft a device that will cheer him up.

Inside his lab, Stimpy operates machinery and uses live animals for his project, periodically drinking his own sweat collected from his glasses. After several failures, he perfects the Happy Helmet, a headpiece that brainwashes its user into a state of forced happiness. He clamps it onto Ren, who protests but quickly succumbs, cheerfully doing housework for Stimpy's amusement. Later, Stimpy brings home a vinyl record of "Happy Happy Joy Joy" by the fictional folk singer Stinky Whizzleteats.

As the two dance to the tune, Stimpy gets distracted, giving Ren a chance to grab a hammer from the kitchen. Ren smashes his own head, destroying the helmet. Freed from its control, a furious Ren grabs Stimpy and starts choking him, but stops when he realizes he actually likes being angry, leaving Stimpy bewildered.

Production

The production of "Stimpy's Invention" stretched over an unusually long period, starting in February 1991 and finally airing a full year later in February 1992. The concept first emerged in 1990 when Bob Camp came up with a story where Ren becomes the victim of one of Stimpy's useless gadgets. John Kricfalusi took a strong interest in Camp’s idea. Camp later recalled that Kricfalusi became completely absorbed in the project, polishing every small detail until he was satisfied.

Kricfalusi then shifted the plot by suggesting that Ren should suffer a mental collapse, which leads Stimpy to build the Happy Helmet—a device meant to fix him, but instead takes control of him as he fights to break free. The network executives wanted a specific scene included: Stimpy using a duck as a tool, Ren hitting Stimpy with a folded newspaper, and Stimpy grinning so widely that the top of his head separates from his lower jaw. Although some of the more over-the-top elements were cut, much of what the executives objected to still made it into the final version.

In a 2008 interview, Kricfalusi said he had to push hard to get producer Vanessa Coffey to greenlight the episode, and the team lost a month due to problems outside their control. He also noted that both "Space Madness" and "Stimpy's Invention" were turned down by Nickelodeon at first before he managed to change their minds. Looking back, these two episodes are often regarded as the show’s most popular. Vincent Waller explained that Nickelodeon’s executives did not like Stimpy using a duck to build the Happy Helmet, worried that kids might copy the scene and use ducks as tools.

They would have preferred a woodpecker instead. According to Waller, there was also concern that the scene was too cruel to the duck, since its head would be banged against hard metal. Kricfalusi responded with a memo stating that the animation team would draw a duck anyway. As he put it, he simply sent back a note that said, "No."

Reception

Thad Komorowski, an American scholar, awarded the episode a perfect five-star rating, calling it one of the series' best for its "ideal balance of genuine turmoil with uproarious comedy." Journalist Joey Anuff described "Stimpy's Invention" as creator John Kricfalusi's "finest moment." Critic Dawn Taylor, reviewing the first two seasons on DVD, ranked it among the show's top episodes, highlighting the "dastardly catchy Happy Happy Joy Joy song." She also pointed out that the psychotic rant from the Burl Ives–like character Stinky Wizzleteats uses dialogue Ives originally spoke in the 1958 film The Big Country.

Scholar Sarah Banet-Weiser noted that the episode, upon its 1992 premiere, offered a refreshing break from the bland cartoons of the 1980s. She observed that lines like Ren's threat, "You filthy swine, I will kill you!" would never have aired in a 1980s cartoon. Banet-Weiser also remarked on the episode's cheerful satire of modern American culture, such as Stimpy using a duck and a beaver as tools to mock the "no testing on animals" disclaimer common in marketing.

Furthermore, she noted that the episode lampoons happiness and conformity: Ren finds joy only in being unhappy, and the Happy Helmet becomes a form of slavery, stripping Ren of control over his mind and emotions once Stimpy places it on his head.
