During morning break, the naughty boy at school drew an erect penis on the blackboard.

The lady teacher, horrified, instantly rubbed it off.

The very next day, the same boy drew an even bigger penis.

Underneath his large drawing he wrote:

'REMEMBER, THE MORE YOU RUB, THE BIGGER IT GETS!' 

A girl realised that she had grown hair between her legs.

She became worried and asked her mum about that hair.

Her mum calmly said, "That part, where the hair has grown, is called Monkey, be proud that

your Monkey has grown hair." The girl smiled and instantly felt proud.

At dinner, she told her sister, "My Monkey has grown hair."

Her sister smiled and replied, "That's nothing, mine is already eating bananas."
