Inspector Gadget debuted as an animated television series in 1983, following a clumsy cyborg detective whose gadgets always malfunctioned at the worst moment. Its theme music became one of the most recognisable cartoon jingles of the decade, endlessly replayed in reruns and home video releases. The tune later resurfaced online, where meme makers adopted it as shorthand for botched investigations and mock-serious detective work. Decades on, it still signals instant cartoon nostalgia and a case about to go hilariously wrong.
