123 Kind of willies

The daughter asks, "Mom, how many different kinds of willies are there?" The mother smiles and says, "Well, dear, a man goes through three phases also. In his 20s, his willy is like an oak tree, mighty and hard. In his 30s and 40s, it's like a birch, flexible but reliable. After his 50s, it's like a Christmas tree." "A Christmas tree?" the daughter asks. "Yes, dead from the root up and the balls are just for decoration."
