Little Johnny Joke

While out shopping with his mother Little Johnny puts his hand up a mannequin's skirt. His mom smacks his hand and says "Don't do that, there's teeth up there, they'll bite your fingers off". Years later when Little Johnny gets a girlfriend and they start making out she whispers to him "You can put your hand in my pants if you like" He says "No chance, you've got teeth in there that'll bite my fingers off" She replies "Don't be so silly, there's no teeth up there, look" and drops her underwear. "Ha!" said Little Johnny, "I'm not surprised, look at the state of your gums"
