Animal Rights

A blonde was taking a walk in the country. Suddenly, she noticed something that intrigued her. In the middle of the field, chewing grass lazily, there was a cow with no horns.
As she kept walking, she noticed a farmer tending to the rest of the herd. She asked him: “Excuse me, can you tell me why that cow doesn’t have any horns?”
“Well miss,” the farmer started, “cattle can do damage with their horns so we usually keep them trimmed down with a hacksaw.”
Horrified, the blonde exclaimed, “A hacksaw? But that’s just inhumane.”
The farmer continued, “You can also treat young calves with special chemicals so their horns never grow.”
Still shocked, the blonde gasped “Well, that’s not much better either. So can you tell me how that poor cow lost its horns?” She pointed to the cow she saw first.
The farmer looked to where she pointed, smiled and said, “Well miss, that cow doesn’t have any horns because it’s a horse!”
