A young man asks his father, "Dad, how many kinds of breasts are there?" The father, surprised, answers: "Well, son, there are three kinds of breasts. In her twenties, a woman's breasts are like melons, round and firm. In her thirties to forties, they are like pears, still nice but hanging a bit. After fifty, they are like onions." "Onions?" "Yes, see them and they make you cry."
