A Jew, a Hindu and an Irishman were travelling together, and as the night fell they came to a little country inn. The innkeeper explained apologetically that only two beds were available in the inn, but he would be glad to make up a comfortable cot for the third man in the barn. So the three travellers drew straws, and it fell upon the Jew to sleep in the barn.
In a few minutes there was a knock at the door, to which the innkeeper responded.
"I'm so sorry," explained the Jew, "but there is a big pig in the barn, and my religion forbids me to sleep under the same roof as a pig!"
The Hindu had taken the next straw, and out he went. In a few minutes there was another knock at the door, and the innkeeper opened the door on the Indian fellow. Apologising gracefully, he explained that his religious belief forbade him to share shelter with a cow, and there was in the barn.
Finally, out went the Irishman. In a few minutes there was yet another knock at the door, which the innkeeper answered. On the doorstep stood the pig and cow!
