A lawyer, a Rabbi and a Hindu holy man had car trouble in the countryside and asked to spend the night with a farmer. The farmer said
There might be a problem; you see, I only have room for two to sleep, so one of you must sleep in the barn.
No problem, chimed the Rabbi,
My people wandered in the desert for forty years, I am humble enough to sleep in the barn for an evening. With that he departed to the barn and the others bedded down for the night.
Moments later a knock was heard at the door; the farmer opened the door, there stood the Rabbi from the barn.
What's wrong? asked the farmer.
The Rabbi replied,
I am grateful to you, but I can't sleep in the barn. There is a pig in the barn and my faith believes that this is an unclean animal.
His Hindu friend agrees to swap places with him. But a few minutes later the same scene reoccurs. There is a knock on the door,
What's wrong, now? the farmer asks.
The Hindu holy man replies,
I too am grateful for your helping us out but there is a cow in the barn and in my country cows are considered sacred. I can't sleep on holy ground!
Well, that leaves only the lawyer to make the change. He grumbled and complained, but went out to the barn. Yep, you guessed it! Moments later there was another knock on the farmers door. Frustrated and tired, the farmer opens the door, and there stood the pig and the cow.
