A blonde bought two horses........

A blonde bought two horses, and could never remember which was which.
A neighbor suggested that she cut the tail of one horse and that worked
great until the other horse got his tail caught in a bush. It tore just
right and looked exactly like the other horse's tail and our friend was
stuck again.

The neighbor suggested she notch the ear off one horse. That worked fine
until the other horse caught his ear on a barbed wire fence. Once again
our friend couldn't tell them apart. The neighbor suggested she measure
the horses for height. When she did, she was very pleased to find that
the white horse was 2 inches taller than the black.
