After some intense pondering I've finally been able to narrow it down. Alas, my top five favorite/funniest bumper stickers...
No. 5) Jesus was my copilot but we crashed into a mountain and I had to eat him.
No. 4) What if the Hokey Pokey IS what it's all about?
No. 3) Pretty much anything with Calvin peeing on it.
No. 2) Mondale / Ferraro '84
No. 1) Honk in you want to see my finger.
Honorable mention based on cleverness) ROCK IS DEAD! long live scissors paper.
