Tales of the Unexpected

Roald's Introduction 

"I personally think this story is funny.  If your sense of humor doesn't happen to be the same as mine, then I'm afraid you're going to be a bit disturbed by what goes on.  And by the way, if any of you are tempted to think it's all pretty far fetched, then you should stop, and think, and ask yourself seriously whether such a thing as this could really happen.  The answer is yes.  Of course it could.  Even to you."
