A farmer is walking with a prospective buyer when they see a beautiful pig in the yard, except it has a wooden leg. The buyer asks, "Why the wooden leg?"

The farmer replies, "That pig is so smart, I let it drive the kids to school."

"Great, but why the wooden leg?"

"The pig is so smart it has a degree in horticulture and philosophy."

"Amazing! But why the bloody wooden leg?"

"Well when you have a pig that smart, you don't eat it all at once!"
