Never Gonna Give You Up was released by Rick Astley in 1987 as the lead single from his debut album Whenever You Need Somebody, and it became a worldwide number-one hit. Two decades later, the song was repurposed online as a bait-and-switch prank known as Rickrolling, where a promising link unexpectedly opened the music video instead. The joke spread through forums, YouTube and social media in the late 2000s, and it has endured because the song is genuinely catchy, instantly recognisable and harmless, making the surprise feel playful rather than mean.
