A mother, father and young son are visiting the circus.
The elephants walk out into the circus ring and the little boy says to his mother,
- "What's that?"
- "That's the elephant's tail," she replies.
- "No, under the tail," says the youngster.
The mother is clearly embarrassed and says,
- "Oh, nothing."
The boy turns to his father and repeats the same question. His father looks and says,
- "That's the elephant's penis, son."
- "So, why did mum say it was nothing?" asks the boy.
The father draws himself up to his full height and says, "Son, I've spoiled that woman."
