Late one evening, guy reading the paper hears the doorbell ring. "Who could that be at this hour", he thinks. As he open the door, he,a t first sees nothing. Then he hears ahigh pitched voice saying, "Could you spare a leaf of lettuce or cabbage, I'm really hungry?"... looking down he's surprised to see a snail. The guy's response was to kick the snail about 100 feet into the lawn.
About a year later, again, late at night, the doorbell rings... guy gets up goes to the door and on opening it he sees the snail again... snail says "Was that really neccessary?"....
