what is the craziest song ever stuck in your head?

Last Friday (my birthday, people) I was driving the car somewhere, and therefore listening to the local "we play everything" radio station -- no lie, their catchphrase is "Charlie FM, we play everything". I've never heard Thin White Rope on this station so I disagree with their assertion, BUT you can hear Willie Nelson followed by Twisted Sister followed by New Order followed by Supertramp followed by THIS SONG, which cannot be scrubbed from my brain, no matter how many times I hear the ABC song or Elmo's theme, or some melodramatic classical music on public radio, or an old Thin White Rope cd.
