A farmer and his wife are lying in bed one evening: she was knitting, he was reading the latest issue of Animal Husbandry. He looks up from the pages and says to her, "Did you know that human is the only species in which the female achieves orgasm?" 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."
