A blonde tries to go horseback riding ....

.....
even though she has had no lessons or prior experience.
She mounts the horse unassisted and the horse immediately springs into action. It gallops along at a steady rhythmic pace, but the blonde begins to lose her grip and starts to slide in the saddle.
In terror, she grabs for the mane but can't seem to get a firm grip. She tries to throw her arms around the horses neck, but she slides down the side of the horse anyway. The horse gallops along, seemingly impervious to it's slipping rider.
Unfortunately, the Blonde's foot has become entangled in the stirrup. She is now at the mercy of the hooves as her head is struck against the ground over and over again.
As her head is battered against the ground she is moments away from losing consciousness when, to her great fortune, the Walmart's Manager sees her and unplugs the horse.
