Happy Happy Joy Joy comes from The Ren and Stimpy Show, the Nickelodeon cartoon that premiered in 1991. The song appears in the 1992 episode Stimpy's Invention, where Stimpy forces the miserable Ren to wear a Happy Helmet, with the track credited to fictional folk singer Stinky Wizzleteats. Its repetitive chorus became one of the show's defining catchphrases and a shorthand for forced cheerfulness. Decades later it still circulates in memes and edits because the phrase instantly signals happiness that is clearly not genuine.
