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. Because it is Soooooo much cheaper. So, I figure that if I have to roll my own, SO DOES SHE!
