A young boy was at the zoo with his parents, and when they came to the elephant enclosure the boy asked his mother "Mum whats that hanging down under the elephant?"

"Thats his trunk dear." his mother replied.

"No - further back mum."

"Oh, thats his tail dear."

"No, mum - in front of that."

His mother replied " oh thats nothing dear."

The young boy, unsatisfied with his mum's answer, decided to ask his dad.

"Dad, what is that hanging down under the elephant?"

His dad replied "Thats his cock son."

"When i asked mum what it was she said that it was nothing."

His dad replied "Son, thats because your mum's been spoilt."
