Economical Jokes

A man enters a pharmacy and wanders up and down the aisles. A salesgirl notices him and asks if she can be of help. He says that he's looking for a box of tampons for his wife, so she directs him to the correct aisle.
A few minutes later, he deposits a very large bag of cotton balls and a ball of string on the counter. Confused, the salesgirl says, "Sir, I thought you were looking for some tampons for your wife?"
"Well, it's like this," he replies. "Yesterday, I sent my wife to the store to get me a carton of cigarettes. What does she come home with... a tin of tobacco and some rolling papers because, as she put it, it's more economical. So, I figure if I have to roll my own, then so does she!"
