Abbreviations.

Ask some dignified man to put the tip of his forefinger under his chin. While he holds it there ask him to tell the assembled multitude the abbreviation for quart. He will look the part when he says “Q-t,” which you’ll all agree sounds like “Cutie.”

Later on get some other guest to point his forefinger at his head and show how well educated he is by immediately giving the abbreviation for mountain “M-t.” certainly sounds like “empty” though it would hardly be right for any of the other guests to thus describe the victim’s head!
