Bill woke up one morning, and make his way to the front door to get the newspaper. After opening the door, he reach down for the paper and saw a snail lying on the porch. Bill pick up the snail and threw it across the street.
Two years later, on a Sunday morning, Bill was going through his same routine. Wake up, put on slippers adn a dressing gown, and make his way to the front door to retrieve the paper. When he opened the door, there sat a snail.
The snail look up at Bill and said, "Now, was that REALLY necessary?"
