She advanced to the paying teller's window and, handing in a check for fifty dollars, stated that it was a birthday present from her husband and asked for payment. The teller informed her that she must first endorse it.
"I don't know what you mean," she said hesitatingly.
"Why, you see," he explained, "you must write your name on the back, so that when we return the check to your husband, he will know we have paid you the money."
"Oh, is that all?" she said, relieved.... One minute elapses.
Thus the "endorsement": "Many thanks, dear, I've got the money. Your loving wife, Evelyn."
