Rickrolling began in 2007 as an online bait-and-switch prank, when a disguised link that promised one thing instead opened Rick Astley's 1987 hit Never Gonna Give You Up. The joke spread from forums to YouTube, social media and live events, helped by the song's upbeat chorus and Astley's earnest performance, which made the reveal feel harmless and funny rather than hostile. Variations like this one keep the format fresh by adding a spoken denial first, so even viewers who know the original prank can still be caught out.
