A Jew, a Hindu, and an Irishman were traveling together, and as night fell they came to a little country inn. The innkeeper explained apologetically that only two beds were available in the inn but that he would be glad to make up a comfortable cot for the third man in the barn. So the three travelers drew straws, and it fell upon the Jew to sleep in the barn. In a few minutes there was a knock on the door, to which the innkeeper responded.
"I'm sorry," explained the Jew, "but there is a 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, though, there was another knock, and the innkeeper opened the door on the Indian fellow. Apologizing gracefully,
he explained that his religious persuasion forbade him to share shelter with a cow, and there was indeed such a creature in the barn. Finally, out went the Irishman. In a few minutes there was yet another knock on the door, which the innkeeper answered. On the sill stood the pig and the cow.
