Amid court-ordered busing in the 1970s, a middle-school teacher tried to distract her nervous students on the first day of class with this strange assignment: find a monarch caterpillar. The result? A memorable lesson in the miracle of metamorphosis. Plus, the story behind the slang interjection word!, meaning “believe me!” The original version involved the idea that a person’s word was their bond. And the expression empty wagons make the most noise suggests that the person who boasts the loudest may actually be the least knowledgeable.
