Kinds of stuff

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."

A young woman asks her mother, "Mom, how many kind of penises are there?"

The mother, surprised, answers, "Well, daughter, a man goes through three phases. In a man's twenties, a man's penis is like an oak, mighty and hard. In his thirties and forties, it is like a birch, flexible but reliable. After his fifties, it is like a Christmas tree."

"A Christmas tree?"

"Yes, dried up and the balls are there for decoration only."
