A little boy and his grandfather are raking leaves in the yard.

The little boy sees an earthworm trying to get back into its hole. He says, "Grandpa, I bet I can put that worm back in that hole."

The grandfather replies, "I'll bet you five dollars you can't. It's too wiggly and limp to put back in that tiny hole."

The little boy runs into the house and comes back out with a can of hair spray. He sprays the worm until it is straight and stiff as a board. The boy then proceeds to slip the dying worm back into the hole. The grandfather hands the little boy five dollars, grabs the hair spray and runs into the house.

Thirty minutes later the grandfather comes back out and hands the boy another five dollars. The little boy says, "Grandpa, you already gave me five dollars."

The grandfather replies, "That's from Grandma."
