There was little boy once who was with his mum in the shopping mall.

Now
this kid was looking at the manequins modelling all the womens clothes and
decided to stick his hand up one of their skirts.

He was just about to
when his mum stopped him and told him off. "You can't put your hands up
their skirts," she said.

"Why not?" the little boy asked.

"Because the have teeth up there that will bite you hand off," she said.

Anyway a few years later when he was all grown up and going out with a
girl, his girlfriend told him to stick his hand up her skirt.

"No way," he
said. "I know that you're gonna bite my hand off if I stick it up there,
you got teeth."

"No I don't," she said. "I'll show you."

So she took off all her clothes and stood there in front of him and said,"See, I told you I don't have teeth!"

He replied with, "No wonder you don't have teeth with gums like those."
