Never Gonna Give You Up was released by Rick Astley in 1987 as a chart-topping pop single, but its second life began in 2007 when internet users started disguising links to its music video as something else entirely. The bait-and-switch prank, soon known as Rickrolling, spread through forums, social media and video platforms, becoming one of the internet's longest-running jokes. It endures because the song is upbeat, instantly recognisable and harmless, making the reveal funny rather than annoying for most people who fall for it.
