Except for the annoying commentary, that was just awesome. And why shouldn't he have a sense of humor? Who would have thought people would know the name Rick Astley in 2008? He got another 15 minutes of fame out of it.

I got Rickrolled once and should have known better. Someone had a deleted interrogation scene from Dark Knight on YouTube, and had put several seconds of a still frame of Batman standing behind Joker at the precise middle of the video, so the preview image YouTube generated was that shot, and not anything that would give it away. I thought that was well done.
