A restaurant put an ad  on a paper- We will make anything you order.  If we cannot make it, we will pay you $50.00.

A man wanted quick $50, he went to the store, called a waiter, thought for a long time to make sure whatever he ordered cannot be filled, and finally said in a loud voice, "Make me elephant's ear's sandwich."

"Oh No," said the waiter, "That we cannot make it.  Ok you win, we will pay you $50.

The man was pleased with himself. "So..", he said with a winning smile, " You do not have elephant's ear. Huh??!"

"Actually we do have elephant's ear, Sir", waiter said apologetically," but we just ran out of "big bread" to make its sandwich."
