Hairspray And Worms

Grandad was at his sons house playing wth his grandson in the back garden. The grandson is looking down at something on the grass and grandad asks him what he is looking at. The grandson points to a worm and asks grandad "what's that"?

Grandad explains that it is a worm, a very wiggly creature who live underground in a hole. Grandad says to his grandson that it can be very difficult to get the worm back in its hole, but if he can thing of a way to achieve that grandad would give grandson a dollar.

Grandson thinks for a minute then runs back into the house. He reappears a couple of minutes later with his mums hairspray, lays the worm out flat on the ground and gives it a good spray. The worm is then stiff and allows the grandson to pick up the stiff worm and slide it back into its hole.  

Grandad is very impressed and takes a dollar out of his pocket and gives it to grandson.  

The next day grandad comes round to visit grandson again, and gives him five dollars from grandma....
