A man walks into a pharmacy and wanders up and down the aisles.

The salesgirl notices him and asks if she can help him.

He answers that he looking for a box of tampons for his wife. She directs down the correct aisle. A few minutes later, he deposits a huge bag of cotton balls on the counter.

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

"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, she too can roll her own."
