Three men were travelling in rural America when their car came to grief, whereupon they sought shelter at the nearest farmhouse.
The farmer had two spare beds, and, of course, his daughter’s, but since he had heard all of those stories he informed the men that one of them would have to sleep in the barn. One of them, a very polite Hindu mathematician, immediately volunteered and went out to the barn. A short time later there was a knock on the door, and, sure enough, there was the Hindu, very apologetically explaining that there were cows in the barn, and because of his religious convictions, he didn’t think he could remain there.
A second man, a conservative rabbi, now volunteered and went. But a short time later, there was a knock on the door. Sure enough, he too was back, explaining that since there was a pig in the barn, he too would be quite uncomfortable out there.
Whereupon the third man, a practising lawyer, agreeably proceeded out to the barn.
In a little while, there was a knock on the door. And when they went to answer it, sure enough, there were the cows and the pig.
