A visitor to the North Pole was given the grand tour of the place by Santa Claus.

The visitor suddenly exclaimed, "What a huge reindeer! But why doesn't it have any antlers?"

Santa replied, "Well, there are several reasons that a reindeer might not have antlers. Some reindeer get their antlers late, some reindeer have their antlers broken off in a fight and some reindeer never grow any antlers at all."

The tourist moved closer for a better look and asked, "What happened to this one?"

Santa replied, from fifty yards away, "He was born a horse."
