Olga Nunes and Elaine Doyle were so inspired by this xkcd comic that they set it to music, and they managed to talk a bunch of famous geeks into singing along. Neil Gaiman, Wil Wheaton, Cory Doctorow (in cape and goggles), Patrick & Teresa Nielsen Hayden, and loads of others are featured.

See Olga’s site for the whole list.

And now try to get that song out of your head.
