COUNTING OUT

THIS VERSE WAS USED TO ELIMINATE PEOPLE IN ORDER TO FIND
OUT WHO WOULD BE "IT" FOR SOME GAME:
ENGINE, ENGINE NUMBER NINE,
RIDING DOWN CHICAGO LINE.
IF THE TRAIN GOES OFF THE TRACK,
DO YOU WANT YOUR MONEY BACK?
PERSON WHO IS POINTED TO ON THE WORD "BACK" SAYS EITHER
YES OR NO.
Y-E-S SPELLS YES, AND OUT YOU DO GO.
(N-O SPELLS NO AND OUT YOU DO GO)
