Tell The Difference

A neighbor suggested that she cut off the tail of one horse, which worked great until the other horse got his tail caught in a bush. The second horse's tail tore in the same place and looked exactly like the other horse's tail. Our blonde friend was stuck again.

The neighbor then suggested that she notch the ear of one horse, which worked fine until the other horse caught his ear on a barbed wire fence. Once again, our blonde friend couldn't tell the two horses apart.

The neighbor then suggested that she measure the horses for height.

When she did that, the blonde was very pleased to find that the white horse was 2 inches taller than the black one.
