Phases of Boobs and Penises

A family was at the dinner table.

Son asked his father: Dad, how many kinds of boobs are there?

Surprised father answered: Well, son, there are three kinds of boobs.
In her 20's, a woman's are like melons, round and firm.
In her 30's to 40's, they are like pears, still nice but hanging a bit.
And after 50, they are like onions.

Son: Onions!!??

Father: Yes, you see them and they make you cry.

This made his wife and daughter mad. So the daughter asked her mom: How many kinds of penises are there?

The mother smiled and answered: Well dear, a man goes through three phases...
In his 20's, his penis is like an oak tree, mighty and hard.
In his 30's and 40's, it is like a birch, flexible but reliable.
And after his 50's, it is like a christmas tree.

Daughter: A christmas tree!!??

Mom: Yes, the tree is dead and the balls are just for decoration.
