A farmer was in the pub bragging about his pig.

"That animal saved my life twice," he said. "Once I fell into the river, and he jumped in and dragged me to the bank. Another time my house caught on fire, and he ran in and saved me, the wife, and kids."

The farmer passed around a picture of the miraculous animal. One of the guys noticed that the pig was missing a leg.

"Which accident did the pig lose its leg in?" he asked.

"Neither. An animal like that you don't eat all at once."
