I have that nuclear cartoon on a coffee cup, QB. Love it.
My all-time fave Larson is where a boy and his dad are looking over the fence at the house next door, where a wolf, a lion and assorted other mean animals are prowling around and going in and out of the house. Dad says to the boy, "Bobby, I know you miss the Wainrights, but they were weak and stupid people and that's why we have wolves and other large predators."
