Klasky Csupo was the Los Angeles animation studio behind 1990s Nickelodeon hits such as Rugrats and Aaahh!!! Real Monsters, and its animated logo sting became instantly recognisable to children who grew up watching those shows. Years later, internet creators began re-uploading the sting with extreme volume and distortion, turning a nostalgic ident into an earrape meme. That contrast between a familiar childhood sound and an aggressively loud edit is why it still circulates on soundboards, in meme videos and as a prank clip.
