A recent (insert your favorite college here) graduate decides to try horseback riding, even though she has had no classroom lessons to train her for this experience. She mounts the horse, unassisted, and the horse immediately springs into motion. It gallops along at a steady and rhythmic pace, but the gal 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 horse'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, the poor girl attempts to leap away from the horse and throw herself to safety.Unfortunately, her foot has become entangled in the stirrup; she is now at the mercy of the horse's pounding hooves as her head is struck against the ground over and over. As her head is battered against the ground, she is mere moments away from unconsciousness, when to her great fortune -- Frank, the Wal-Mart greeter, sees her, rushes over and unplugs the horse.
