Tell Two Horses Apart

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 her to notch the ear of one horse. That
worked fine until the other horse caught his ear on a barbed
wire fence. Once again the blonde 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.
