A man walks into a pharmacy and wanders up and down the aisles.
The salesgirl notices him and asks him if she can help him. He
answers that he is looking for a box of tampons for his wife. She
directs him down the correct aisle. A few minutes later, he
deposits a huge bag of cotton balls and a ball of string on the
counter.

She says, confused, “Sir, I thought you were looking for some
tampons for your wife?

He answers, “You see, it’s like this; yesterday, I sent my wife to
the store to get me a carton of cigarettes and she came home with a
tin of tobacco and some rolling papers. So, I figure that if I have
to roll my own, SO DOES SHE!”
