A little boy is waiting for his mom to come out of the changing room while shopping with her. The little boy gets bored and when his mom comes out, she finds him sliding his hand up a mannequin's skirt.
'Get your hand out of there!' she shouts. 'Don't you know that women have teeth down there?'
The little boy quickly snatches his hand away and thanks his lucky stars he didn't get bitten. For the next ten years, this little boy grows up thinking all women have teeth between their legs.
When he's 16, he finds himself a girl. One night, while her parents are out of town, she invites him over for a little action. After an hour of making out and grinding on the sofa, she says 'you know, you could go a little further if you want.'
'What do you mean?' he asks.
'Well, why don't you put your hand down there?' she says, pointing to her crotch.
'Hell no,' he cries, 'you've got teeth down there.'
'Don't be ridiculous,' she responds, 'there's no teeth there.'
'Yes there are,' he says, 'my mom told me so.'
'No there aren't,' she insists. 'Here, look for yourself.'
With that, she pulls down her pants and gives him a little peek.
'No I'm sorry' he says. 'My mom already told me that all women have teeth down there.'
'Oh for Christ's sake!' she cries. She whips off her panties, throws her legs behind her head, and says, 'Look, I don't have any teeth down there.'
The boy takes a good long look, then replies: 'Well, with the condition of those gums I'm not surprised.'
