Blonde Horse Ranch
A blonde had two horses, but she couldn't tell them apart. So she
asked her neighbor for advice. He suggested that she cut the tail
off one of the horses. This worked until the other horse snagged
his tail on a fence. So the neighbor suggested notching one of the
horses' ear. This worked until the other horse snagged his ear on a
fence. So the neighbor suggested measuring the heights of the
horses. And sure enough, the white horse was two inches taller than
the black horse.
