Its quite funny actually, its Baby Got Back as sung by Jonathan Coulton. If you don't know what song that is, its "I like big butts and I can not lie." I threw a few random pictures of JC into the mix just so you've got something other than a black screen to look at. There are about 10 pictures and they'll just loop over til the end of the song.

As far as I know. (And according to his website) Jonathan Coulton's MP3's are free. So you are allowed to get this and distibute. Well, don't take my word for it. Here's a link to his website where it says it. http://www.jonathancoulton.com/primer/get/
