In freshman year, I had a roommate who couldn't fall asleep unless she was watching her Golden Girls dvds. In the middle of the night, I would wake up to the menu screen playing the theme song over and over again. I think that must be what hell is like.
The worst? Maybe, maybe not. But here's a bunch performed by The Blanks (aka Worthless Peons). http://youtu.be/UkAJSxaFq0w Not all themes, but all funny.
