In the Old West a wagon train is crossing the plains.  As night falls the
wagon train forms a circle, and a campfire is lit in the middle.  After
everyone has gone to sleep two lone cavalry officers stand watch over the
camp.
	After several hours of quiet, they hear war drums starting from
a nearby Indian village they had passed during the day.  The drums get
louder and louder.
	Finally one soldier turns to the other and says, "I don't like
the sound of those drums."
	Suddenly, they hear a cry come from the Indian camp:  "IT'S
NOT OUR REGULAR DRUMMER."
