Continuing with the theme of "mixing" music below, there's this guy named RX (that's all he goes by) that is a genius of editing the comments of George Bush and overlaying them upon popular songs.

The song is here.
Remember Kids, Don't Do Drugs.
(Also, you might want to download "My Generation" which includes Bush, Hillary, and Bill).
