A couple take on an 18 year old girl as a lodger.
She asked if she could have a bath but the woman of the house
told her they didn't have a bathroom and she could use a tin bath in front of the fire.

"Monday's the best night, when my husband goes out to play darts," she said, so the girl agreed to have a bath the following Monday.

After her husband had gone to the pub for his darts match, the
woman filled the bath and watched as the girl got undressed. She was surprised to see that the lass didn't have any pubic hair and told her husband when he came home.

He didn't believe her so she said, "Next week I'll leave a gap in the curtains so that you can see for yourself."

The following Monday, while the girl again got undressed, the wife
asked, "Do you shave?"

"No," replied the girl. "I've just never grown any hairs down there.
Do you have hairs?"

"Oh yes," said the woman and she showed off her great, hairy
muff.

When the husband got back in she asked, "Did you see it?"

"Yes," he said. "But why the hell did you have to show her yours?"

"Why not?" she said. "You've seen it all before."

"I know," he said, "but the fu*king darts team hadn't!"
