Sleep in the barn
 

A Rabbi, a Hindu, and Obama are in a car.

They run out of gas and are forced to stop at a farmer's house.
The farmer gladly accommodates them, but tells them that there
are only two extra beds, so one person will have to sleep in the
barn.

The Hindu says, "I'm humble, I will sleep in the barn." So, he
goes out to the barn.

In a few minutes, the farmer hears a knock on the door.
It's the Hindu. He says "There is a cow in the barn.
It's against my beliefs to sleep with a cow."

So, the Rabbi says, "I'm humble, I'll sleep in the barn."

A few minutes later, the farmer hears another knock on the door
and it's the Rabbi. He says that it is against his beliefs to sleep
where there is a pig, and there is a pig in the barn.

So, Obama is forced to sleep in the barn.

A few minutes later, there is a knock on the door.
It's the pig and the cow...

Thanks Karl, cannot blame the cow and pig!
