The Heroic Walmart Greeter.

  A blonde decides to try horseback riding, even though she has
had no lessons 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 slide 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 horse's side
anyway. The horse gallops along, seemingly oblivious of its slipping
rider
Finally, giving up her frail grip, the blond 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 dilemma and unplugs the horse.
And you thought all they did was say Hello.
