Never Gonna Give You Up was released by Rick Astley in 1987 and became a worldwide pop hit long before it became a meme. In the late 2000s, internet users began sharing the song as a bait-and-switch prank, posting links that promised one thing and opened the music video instead. The joke spread through forums, social media and video platforms, helped by how recognisable the intro is within seconds. It endures because the prank is harmless, instantly understood and still catches new audiences by surprise.
