"Can of Hair Spray" joke
A grandfather and his grandson are raking leaves in the yard when the young boy sees an earthworm trying to get back into its hole.
"Hey, Grandpa," the little boy says, "I bet I can put that worm back in that hole."
"I'll bet you five dollars that you can't," replies the grandfather. "It's much too wiggly and limp to put back in that little hole."
The little boy runs into the house and comes back out with a can of hair spray. He then sprays the worm until it's straight and stiff as a board. Picking it up, he stuffs the worm back into the hole. The grandfather gives the little boy five dollars, grabs the can of hair spray and races into the house.
Some time later, the grandfather comes back out and hands the little boy another five dollars.
"But Grandpa, you already gave me five dollars," the little boy says.
"Yes, I know," replies the grandfather. "That's from your Grandma."
