Sleeping In The Barn

Three men are driving in a car when it breaks down on an abandoned road: A
Hindu man, a Jewish man, and a Polish man. After walking for a few miles, they
come across a farm with a barn. Desperately seeking a place to sleep for the
night, they knock on the door and ask the farmer if they can sleep in the barn.
The farmer says it's OK as long as they don't disturb his sleep or the
animals, so the three men go to sleep in the barn with all the animals.
Fifteen minutes later, the Hindu man bangs on the farmer's door and asks if
he can sleep on the floor of his room, because he cannot sleep with sacred cows
next to him. The farmer says it's OK and lets him in.
In another fifteen minutes, the Jewish man bangs on the farmer's door and
asks if he can sleep on the floor of his room, because he cannot sleep with pigs
next to him, and the farmer says this is OK. Now only the Polish man is outside.
Fifteen minutes later, the farmer hears another knock on the door, and by
this time is very annoyed. He opens it, and there stand the cows and the pigs...
