Blonde On Horse

A blonde decides to try horseback riding, even though she has had no
lessons, nor 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 blonde 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
to its slipping rider. 
  
Finally, giving up her frail grip, the blonde 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.
