A pilot was transporting a bunch of madmen from Tamale to a psychiatric facility in Accra.
The madmen were making noise.
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 very quiet!
PILOT: Wow!! How did you get them to keep quiet?
MADMAN: I opened the door and asked them to
go and play outside.  
