Oscar the Grouch is the grumpy green character from Sesame Street who lives inside a trash can, and the clatter of that can has become one of his most recognisable trademarks. The character has appeared on the children's television series since its early years, with his can serving as both home and comic prop for jokes about mess, grumpiness and unwanted visitors. Online, clips of the can crashing have been lifted from the show and shared as meme sounds, where creators reuse the noise far beyond its original children's television context to signal chaos, failure or a gross punchline.
