The grandfatherreplies, "I'll bet you five dollars you can't. It's too wiggly and limpto put back in that little hole."
The little boy runs into the house and comes back out with a can ofhairspray. He sprays the worm until it is straight and stiff as a board.Then he puts the worm back into the hole.
The grandfather hands the little boy five dollars, grabs the hairspray,and runs into the house. Thirty minutes later the grandfather comes backout and hands the little boy another five dollars. The little boy says,
"Grandpa, you already gave me five dollars."
The grandfather replies, "I know. That's from your grandma.
