I heard of a story of a very similar trio. Rabbi, Irishman and Indian fellow traveling across the farm belt when their car breaks down. They find shelter for the night at a nearby farm house. The famer says though, "Can only put up two of you in the house, one of you gets the barn". Indian fellow say he'll go. Lights out and a few minutes later, there is a banging on the farmhouse door. Farmer answers the door and sees it is the Indian fellow, who says, "Can't sleep in the barn, cow in there, sacred in my religion". The rabbi says OK, he'll go. Few minutes later, Bang! Bang! on the door. Farmer gets up to see the rabbi there. Rabbi says, "Pig in the barn, can't sleep in there". The exasperated Irishman says "OK OK OK, let's get some sleep, I'll sleep in the barn!" Few minutes later, Bang! Bang! on the front door. The farmer drags himself up and opens the front door and there's a pig and a cow standing there.
