A one-armed man entered a restaurant at noon and seated himself next to a dapper little other-people's-business man. The latter at once noticed his neighbor's left sleeve hanging loose and kept eying it in a how-did-it-happen sort of a way. The one-armed man paid no attention to him but kept on eating with his one hand. Finally the inquisitive one could stand it no longer. He changed his position a little, cleared his throat, and said: "I beg pardon, sir, but I see you have lost an arm."
The one-armed man picked up his sleeve with his right hand and peered anxiously into it. "Bless my soul!" he exclaimed, looking up with great surprise. "I do believe you're right."
