Who'd have imagined that one of the biggest Internet memes would feature an '80s music video from a long-retired British pop singer? In 2007, Rick Astley's 1987 sugary hit single "Never Gonna Give You Up
" became a Web phenom of the bait-and-switch variety. If you've been "rickrolled"--and who hasn't?--you know the drill: Click a seemingly relevant link on a particular subject and—wham!
—you're treated to Astley's perky dance video instead. The prank peaked in late 2008 when Astley himself participated in a live rickroll
during the Macy's Thanksgiving Day Parade. While rickrolling still happens today, it's less likely to tell a lie and hurt you.
