Here's a thing that still amazes me: a joke invented by anonymous strangers on a message board in 2007 is now understood by people who weren't even born when it started. Grandparents have been rickrolled. Politicians have been rickrolled. The joke has outlived entire social networks. So how did we get here? It starts, weirdly, with a duck.

First, there was the duck

Before rickrolling there was “duckrolling.” On the imageboard 4chan, somebody set up a running gag where a link that promised one thing would instead dump you on a picture of a duck fitted with little wheels. That's it. That's the whole joke. But it established the format that mattered: promise one thing, deliver something gloriously unrelated. The comedy lived entirely in the gap between what you expected and what you got.

Then someone swapped the duck for a song

In the spring of 2007, the internet was buzzing about a hotly anticipated video game trailer. Someone posted a link claiming to be that trailer. It was not. It was, of course, the music video for Rick Astley's endlessly upbeat 1987 hit. The mismatch — you wanted an action-packed trailer, you got a beaming man in a trench coat dancing his heart out — was perfect. People started doing it everywhere, and because “you've been duckrolled” didn't quite fit anymore, a new word was born: rickrolled.

The moments that made it huge

Most in-jokes stay in their corner of the internet. The rickroll broke out because of a few gloriously public stunts. On April Fools' Day in 2008, a major video site quietly rigged its front-page links so that every one of them led to the video — rickrolling a genuinely enormous audience in a single day. Later that year, Rick Astley himself popped up at a huge televised parade and performed the song live, ambushing millions of viewers at home. When the man behind the meme joins in on the joke, the joke becomes unstoppable.

Why it never died

Plenty of memes flare up and vanish in a week. The rickroll stuck around for three simple reasons. It's harmless, so nobody feels genuinely cheated. It's infinitely reusable, because any link can secretly be a rickroll. And the artist leaned all the way in rather than fighting it, which turned a potential annoyance into a warm, shared tradition. The original video has since sailed past a billion views — a decent chunk of which are people who clicked expecting literally anything else. That's the beautiful absurdity of it: a prank so gentle that getting caught by it is basically a rite of passage.
