Buying Tampons

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 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 paper. So, I figure that if I have to roll my own, SO DOES SHE!"
