She looks at him wistfully, smiles, and replies, "Oh yeah? Prove it."

He frowns for a moment, then says, "O.K." He then gets up and walks out, leaving his wife with a confused look on her face.

About half an hour later he returns all tired and sweaty and says, "Well, I'm sure the cow and sheep didn't, but the way that pig squealed, it's hard to tell."

So, why's the farmer need to be from Massachusetts?
