Rickrolling began in 2007 on forums like 4chan, adapting an earlier bait and switch prank by linking to Rick Astley's 1987 hit Never Gonna Give You Up instead of the promised content. The joke exploded on YouTube and across social media, turning the earnest pop video into one of the internet's most durable memes. Astley himself later embraced it, even performing it live for prank events. Decades after release, the song remains a harmless, instantly understood trick that signals the viewer has been playfully fooled.
