I don't have them , I just thought maybe we could beat Letterman to the punch and come up with the Top Ten Rush Limbaugh Excuses for Mocking Michael J. Fox: 10. Rush wasn't imitating Fox's shaking; he swallowed one of his cigars and had a violent nicotine spaz-out. 9. Viagra overdose made every part of him want to stand up. 8. He was being mugged by The Invisible Man during the broadcast. 7. Rush wasn't shaking...that's just what Jell-O does when it moves. Okay, I started. Now it's your turn.
