A little boy and his grandfather rake 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 little hole."The little boy runs into the house and comes back out with a jar of chocolate ice cream topping. He coats the earthworm in the sauce until it is straight and stiff in a hard chocolate shell. Then he stuffs the worm back into the hole. The grandfather hands the little boy five dollars, grabs the chocolate sauce and runs into the house. Thirty minutes later, the grandfather comes back out 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."
