A Hindu Priest, a Rabbi and a Lawyer were all traveling together and came upon an Inn with only two available rooms. The Innkeeper said that one of them must volunteer to sleep in the barn.

The Hindu volunteered but two minutes later there was a knock at the door. The Hindu Priest said I can not sleep in the barn because there is a cow there.

The Rabbi then volunteered to sleep in the barn. Two minutes later there was another knock at the door. The Rabbi returned saying I can not sleep in the barn because there is a pig in there.

The lawyer then volunteered to sleep in the barn. Two minutes later there was a knock at the door. It was the cow and the pig.
