A man walks into a pharmacy and wanders up and down the aisles. The sales girl 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. The sales girl 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 back with a tin of tobacco and some rolling papers; cause it's so much cheaper. So, I figure if I have to roll my own... so does she."
