Rickrolling!

Thanks to a very common Internet prank called Rickrolling, the music video for singer Rick Astley's 1987 song "Never Gonna Give You Up" is one of the most viewed viral videos ever. Rickrolling is a simple prank—the prankster convinces his or her victim to click a link, telling them it's going to be one thing (like a funny video, an interesting news story, or whatever might interest the victim). But when the prank's victim clicks the link, they are taken to the music video for "Never Gonna Give You Up." That person has just been "Rickroll'd."
