Mahna Mahna became famous through The Muppets, where the shaggy orange character of the same name trades the nonsense phrase with a chorus of pink, horned Snowths who answer with doo-doo-doo-doo-doo. The bit was a recurring musical joke on Muppet television shows, and clips of it kept circulating long after its first broadcasts. Its simple melody and instantly recognisable call-and-response made it easy to quote, remix and drop into short videos, which is why it still works as a shorthand for goofy, carefree fun.
