A man is driving past a farm when he spots a pig with a wooden leg.

Puzzled, he pulls over and approaches the farmer. "What's the story with this pig?" he asks.

"That pig can recognize 100 different commands, work out math equations in the dirt and speak more than 50 words," the farmer says.

"So what's with the wooden leg?" the man asks.

"When a pig is that special," the farmer replies, "You just don't eat him all at once."
