A while back, a researcher reported findings on "stuck tune syndrome," the phenomenon of having a song running through one's head. One way to get rid of it is to tell someone else. So I apologize for announcing this, but I have "I Want a Hippopotamus for Christmas" by Gayla Peevey going through my brain. If you've never heard it, you should probably be thankful. If you're curious, it's on Dr. Demento Presents: The Greatest Christmas Novelty CD of All Time.
