A blond decides to try horseback riding, even though she has had no
 previous or prior experience.  She mounts the horse unassisted and the
 horse immediately springs into motion.  It gallops along at a steady
 and rhythmic pace, but the blond begins to slip from the saddle.
 In terror, she grabs for the horse's mane, but cannot seem to get a
 firm grip.  She tries to throw her arms around the house's neck, but she
 slides down the side of the horse anyway.  The horse gallops along, seemingly
 impervious to its slipping rider.
 Finally, giving up her frail grip, she leaps away from the horse to
 try and throw herself to safety.  Unfortunately, her foot has become
 entangled in the stirrup and she is now at the mercy of the horse's
 pounding hooves as her head is struck against the ground, she is mere
 moments away from unconsciousness when  . . .  . .
 the Wal-Mart manager runs out to shut the horse off.
