The smartest man on Earth (after Stevie Wonder... and Rip Taylor), Stephen Hawking, told the Guardian that he rejects the notion of heaven.
"I regard the brain as a computer which will stop working when its components fail," Hawking told the Guardian. "There is no heaven or afterlife for broken down computers; that is a fairy story for people afraid of the dark."
What do you think of Hawking's declaration?

And, just for good measure...
If there IS a heaven, I hope and pray that I'm greeted by Rip Taylor himself (if he goes first, that is... no pressure, Rip... haaaay!) That's reason enough to behave yourself during your time on this Earth. If Rip's on the other side, be good now, because you do NOT want to miss out on that opportunity.
