One Sunday morning John stepped out onto the porch in his bathrobe to pick up his newspaper. He noticed a snail on the paper, so he picked it up and flung it across the front lawn onto the sidewalk.

Bill looked at the snail. The snail looked at Bill.

Then the snail said: Now, was that REALLY necessary?!
