Last night I was so entranced by Wayne Rooney’s astonishing goal against Manchester City that I embedded a YouTube video clip of it (from a Dutch TV broadcast, judging by the commentary) in a blog post. Clearly, the goal had become a meme, spreading across the Web like that famous clip of Susan Boyle, the singer from nowhere who entranced TV viewers.

You can guess what’s happened to the Rooney clip, can’t you? (Check the post if you’re in any doubt.)
