BonziBuddy was a purple gorilla desktop assistant released in the late 1990s that sat on Windows desktops, told jokes, and spoke in a high-pitched cartoon voice before becoming widely known as adware and being discontinued in the mid-2000s. Its laugh survived long after the program disappeared because early internet users remembered it from shared family computers, and later creators revived it in memes, YouTube edits, and reaction videos as shorthand for awkward, creepy, or mischievous humour. It now works as a piece of retro internet nostalgia.
