Favorite Line?
Mine is probably when he was talking about the moon landing. "I mean, you can't just step onto the moon and say 'Oh, my, it's all sticky.'"
Either that or the bit about Darth Vader's voice. "Yes, the force is quite strong in you." "How strong?" "As strong as a small pony." That one kills me.
On a long enough timeline, the survival rate for everyone drops to zero.
