'Yakko's World' debuted in a 1993 episode of the animated series Animaniacs, with Yakko Warner, voiced by Rob Paulsen, naming roughly 160 nations to the tune of the 'Mexican Hat Dance.' Written by Randy Rogel, the song became one of the show's signature moments and a staple of nineties cartoon nostalgia. Online, short clips of the rapid-fire roll call spread through geography quizzes, reaction videos and meme edits, where the breathless delivery itself became the joke. It remains popular because few sounds convey cheerful, overwhelming speed as instantly.
