Harold Lamb's sense of humor

[On Harold Lamb's birthday today, here is an interesting story about his sense of humor. After the break.]

From the Brooklyn Daily Eagle, Monday, March 11, 1935:

Harold Lamb has a sense of humor .He wrote out the signs used in the street scenes of Paramount's "The Crusades." They are in Persian—and anybody in the audience –who reads Persian will find that one wiggly set of characters means "This Way Out." Another sign, translated, would be, "Pay As You Enter." And still another states "Here Tranquillity Is Desired." Which is the polite Persian way of saying "Silence! This Means You!"
