So they decide to take the innkeeper up on his offer.
The Hindu is the first to speak up.
"I will be the one to sleep in the barn!" he says, and he leaves.
Two minutes later, there's a knock on the door. It's the Hindu.
"There is a cow in the barn, and a cow is holy. I cannot sleep in the barn."
So the Jew steps in.
"I will be the one to sleep in the barn!", and he walks out the door.
Two minutes later, there's a knock at the door. It's the Jew.
"There is a pig in the barn, and a pig is not Kosher. I cannot sleep in the barn."
So at last, the black man offers.
"I will be the one to sleep in the barn!", and he heads outside.
Two minutes later, there's a knock on the door.
It's the cow and the pig.
