Rugrats premiered on Nickelodeon in 1991, created by Arlene Klasky, Gábor Csupó and Paul Germain, and became one of the network's defining animated series. Its opening theme, composed by Mark Mothersbaugh, used playful, offbeat sounds that matched the show's baby's-eye view of the world. The short title card version became a compact nostalgia cue online, shared in meme edits and cartoon compilations long after the original run ended in 2004. Fans still use it to instantly signal early nineties childhood television without needing any dialogue, characters or longer footage from an episode.
