The yodel comes from a classic stock vocal performance by Hannes Schroll, originally recorded for the Goofy cartoon The Art of Skiing in 1941 and later catalogued by Hollywood Edge as a man yodelling effect. That short, instantly recognisable call was reused in later animation, including Ed, Edd n Eddy, where its old-fashioned cartoon energy fitted the show's slapstick tone. Online, creators have kept it alive as a compact reaction sound, sharing it through soundboards and meme edits because it conveys surprise and silliness in well under a second.
