A mum, dad and their son go to the zoo. When they get to the elephants, one walks over in their direction.
The son asks the mother “what’s that hanging done”. The mother says “that’s his trunk”.
“No behind that” says the son. “Oh that’s nothing” replies the mother.
The son then asks the dad, who says “that’s the elephant’s p*nis, son”. “Then why did mummy say it’s nothing?” Asks the boy. “Son, I’ve really spoiled that woman”
