After several years of marriage, a wife was talking to her husband and asked him if she should get a boob job, as she wasn't happy with the size of her breasts. The husband told her they couldn't afford it, but suggested that she rub toilet paper between them several times each day.

She asked "Do you really think that will make them grow bigger?" To which he replied: "Why not? It certainly made your ass get bigger when you did the same thing!"
