Lucky pig

A salesman stops by a farm and is surprised to see a man sitting on the porch with a 3 legged Pig. He asks the man what happened & the farmer replies, "This pig is amazing. Last year, I got drunk & fell into a pond. That pig ran in & pulled me out by the shirt collar. Another time, my tractor rolled over, pinning me down & again, that Pig ran to a neighbor & squealed so loud, they followed it to me, saving my life." The Salesman asks, "But how come the Pig has only 3 legs. The Farmer replies, "Are you kidding. A pig like that, you don't eat all at once."
