Pilot and the Mad Man

A pilot was transporting a bunch of madmen from Lagos to a psychiatric facility in Johannesburg, South Africa. The madmen were making noise and suddenly, one of them entered the Pilot’s Cabin;
MADMAN: Teach me how to fly a plane!
PILOT: I would, but under one condition.
MADMAN: What?
PILOT: If you can get your colleagues to keep quiet.
(5 minutes later, the plane was eerily quiet!)
PILOT: Wow! How did you get them to keep quiet?
MADMAN: I opened the door and asked them to go and play outside!
