The record-scratch stop has been a comedy shorthand for decades, borrowed from DJs and radio presenters who would drag a needle across a record to halt a song mid-play. Television comedies and cartoons adopted the same cue to signal an abrupt change of mood, and editors later carried it into online video, where it became the standard sound for a freeze-frame confession or an awkward interruption. Its popularity endures because the effect needs no explanation: listeners instantly recognise the screech as a full stop, making it a quick, universal way to puncture a scene.
