"A blonde decides to try..." joke

A blonde decides to try horse-back 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 rhythmic and
steady
pace, but the blonde begins to slip in the saddle. In terror, she grabs
for
the horse's mane, but she 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 continues it's galloping pace, seemingly
unaware of
its slipping rider. Finally, giving up her frail grip, she leaps away
from
the horse to try to throw herself to safety. Unfortunately, her foot
becomes entangled in the stirrup and she is now at the mercy of the
horse's
pounding hooves as her head is struck against the ground again and
again.
As her head is being battered against the ground, she is mere moments
away
from unconsciousness when the Wal-Mart manager runs out to shut off the
horse
