A small boy was with his grandfather in the garden when a worm wriggled out from a hole. He told the old man, "I bet you, I can put the worm back into that hole."
"No, you will not be able to do that. The worm is too wriggly and limp," he answered.
The boy ran into the house and came out with a can of hair spray. He hastily sprayed the worm with the chemicals from the can and it became straight and stiff as a board.
The grandfather gave the boy $5. He then took the spray and went into the house. Half an hour later he came out and gave the boy another $5.
The boy said, "But grandpa, you had already paid me."
The grandfather replied, "No, this $5 is from your grandma."
