Klasky Csupo was the animation studio behind many defining Nickelodeon shows of the 1990s, including Rugrats, and its distinctive logo sting played at the end of episodes. As those shows were rediscovered on streaming and shared in clips online, the short jingle became shorthand for 90s childhood nostalgia. Creators now reuse it in memes, compilations and reaction videos to instantly signal retro Nickelodeon, even for viewers who cannot name the studio itself.
