A rabbi, a yogi and a TV evangelist spend a weekend at a retreat in the country. But there are only two beds in each cabin. On the first night, the rabbi says, "I will go sleep in the barn." And he goes out to the barn. A few minutes later, there is a knock on the door. It is the rabbi. "I can't sleep in the barn," he says, " there is a pig out there." Then the yogi says, " Okay, I'll sleep in the barn." And he goes out to the barn. A few minutes later there is a knock on the door. It is the yogi. "I can't sleep in the barn," he says, "there is a cow out there." Then the TV evangelist says, "Okay, I will go sleep in the barn." And he goes out to the barn. A few minutes later there is a knock at the door. It is the pig and the cow.
