There were this group of mad men say about ten of them at a psychiatric hospital. One morning when the doctor arrived the hospital, they were all screaming 'we don well' (for those who don't understand pidgin, it means- we are alright). The doctor was amazed but decided to test their mentality before discharging them. The doctor then drew a vehicle on a board and ask them to make the vehicle move from that position. Nine of the mentally sick men immediatly ran to the board and started pushing the diagram of the vehicle remaining one of them. He(the Dr.) said to himself, this man must really be alright then he asked the man why he was not with the others. The man replied- how can they make the vehicle move without the keys to the vehicle, and that the key of the drawn vehicle is with him.

Funny isn't it?
