He was some kind of singer

From an article on the BBC website about how technology is changing language* comes this brilliant exchange between a web expert and a rather baffled lawyer:

During the trial of the man accused of hacking into Sarah Palin's email account, a guy called  Christopher Poole, who runs a chat website called 4chan, was asked to define various internet-based terms, one of which was the concept of "rickrolling". He explained:

"Rickroll is a meme or internet kind of trend that started on 4chan where users - it's basically a bait and switch. Users link you to a video of Rick Astley performing Never Gonna Give You Up"

And the term "rickroll" - you said it tries to make people go to a site where they think it is going be one thing, but it is a video of Rick Astley, right?," asked the lawyer.

"Yes."

"He was some kind of singer?"

"Yes."

"It's a joke?"

"Yes."

*Ha! see what I did there? Isn't rickrolling HILLARIOUS??!! The real link is here.
