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 sixties, it is like a Christmas tree."
"A Christmas tree?"
"Yes. Dried up, and the balls are there for decoration only."
