I'm not sure what my obsession is with this song, but I'm not alone.  The internets are also obsessed.  In this video, we find Former President Bill Clinton is also obsessed.  Or, at least some great video editing makes it seem that way.

So, he's not really singing. This video is from the guy who brought you Barack Obama Singing Call Me Maybe, "baracksdubs" mashes together presidential speeches to the tune of popular music, based on fan requests. Usually his target is the President, but Bill gets top honors in this one.
