Dexter's Laboratory premiered on Cartoon Network in 1996 as a Hanna-Barbera series created by Genndy Tartakovsky, following Dexter, a child genius who hides a huge laboratory behind his bedroom bookcase. The short laugh became a familiar shorthand for his confidence and mischief, especially in clips shared by fans who grew up with the show. It sits alongside other classic cartoon laughs such as Woody Woodpecker Laugh, and its four-second length makes it easy to reuse in memes, edits and reaction videos.
