blonde horseback riding

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
rhythmic pace, but the blonde begins to slip from the saddle.

In terror she grabs 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, she gives up her frail grasp and 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..... Shadrack, the Pick
'n Pay security guard sees her, leans over, and unplugs the horse.
