By now, most have been successfully rickrolled into a video of Rick Astley's "Never Gonna Give You Up," an 80s classic.  Posing... - Source

The well tread internet joke that Gawker once called the web equivalent of '80s bait "...NOT" should need no explanation by now. But if your mouse has had a sheltered existence, you can find a text summary of the phenomenon here.

And that's Rickrolling: misdirection from an anticipated link, leading you instead to Rick Astley's "Never Gonna Give You Up." It's been a web phenomonen for a good year now -- an update on duckrolling -- and is now transcending the internet to be embraced in entirely new and exciting nerd ways. For instance at sporting events (via NYT)...

The women's basketball game at Eastern Washington University on March 8 started out like any other, as the Eagles of E.W.U. faced off against the Montana State Bobcats.

But a routine timeout turned into a 1980s flashback, as two men on the sidelines briefly hijacked the proceedings with a popular prank known as rickrolling. They surprised the crowd by blasting the British singer Rick Astley's 1987 hit song "Never Gonna Give You Up" through the gym, while one, dressed as a look-alike in Mr. Astley's signature trench coat, lip-synched and mugged to the music.

The NY Times goes even further with the live-action redefinition of the web joke:

Rickrolling has also come to mean a disruptive blast of the Astley song in a variety of situations. Former Scientologists protesting against the church, for example, have been playing and singing the song this year outside Scientology offices in London, Washington, Seattle and other cities.

We provide all this background to say, yes of course we also have wondered what Astley makes of all this. When told about it, does he just awkwardly dance it off in a big trench coat and sunglasses? Or has it gone to his head? The Times says: "It is not clear what Mr. Astley himself thinks about rickrolling. He has not spoken publicly about the meme and efforts to reach him through his agent were unsuccessful."

Fortunately, the LA Times had a little more luck getting their man. - Source
