A couple living in a small Minnesota town 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 as such but she could use a tin bath in front of the fire.
"Monday's the best night, when my husband goes out to bowl," the woman said. So the young girl agreed to have a bath the following Monday night.
After her husband had gone off for his bowling tournament, the woman filled the bath and watched as the girl got undressed.
She was surprised to see that the young 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, when you go off to bowl, I'll leave a little gap in the curtains so that you can see for yourself, alright?"
The following Monday night, while the girl got undressed for her bath, the wife asked her, "Do you shave down there?"
"No," replied the girl, "I've just never grown any hairs down there. Do you have hairs on yours?"
"Oh, yes," said the woman and she showed the girl her hairy muff.
After the girl had gone to bed the husband came home and the wife 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 before."
"I know," he replied, "but the bowling team hadn't!"
