A banker, an engineer and a lawyer were driving down a road when their car stops working.
Seeing a farm house near by, they decide to stop by and ask if they could sleep over night while their car was being repaired.
“Sure”, replied the farmer, “but I only have two spare beds – one of you will have to sleep in the barn.”
The engineer decides that he would do it.
Ten minutes later, there is a knock at the front door.
“I can’t sleep in the barn – there’s a cow in the barn and I am a Hindu.”
So, the banker agrees to sleep in the barn.
Ten minutes later, there is another knock at the door:
“I can’t sleep in the barn – there is a pig in the barn, and I am Jewish.”
The lawyer says “I know what you’re up to, but I’ll go,” and so the lawyer goes out to the barn.
Sure enough, ten minutes later, there is a third knock at the door – the cow and the pig appear.
