A pilot was told to transfer mad people from Nigeria to U.S.A. He agreed and carried them in his plane. The whole plane was so noisy.
Later one of the mad men approached the pilot in the cockpit and asked him, "Please can you teach me how to fly the aeroplane?"
The pilot replied, "I will teach you how to fly if you will tell your friends to stop making noise."
The mad man went back inside the cabin. After some minutes, the whole plane was silent.
Some minutes later the mad man approached the pilot again and told him that everywhere was silent now.
The pilot became happy and asked "WHAT DID YOU DO TO MAKE THEM SO QUIET?"
The mad man replied, "I opened the door for them to go and play outside."
The pilot fainted.
