Every day on my way to work I pass a billboard on the side of a phone booth for the movie version of Underdog.  What this means is that the theme song (which I absolutely love) is stuck in my head for at least an hour -- or until Hold the Line pops back into it.  If you haven't listened to it in a while, I highly recommend it.  And you might want to check out the a cappella version from Scrubs.
