Dr. John Demidowicz, professor emeritus of Spanish, liked to play a little joke on the first day of class. He would let a golf ball slip out of his pocket and tell the students, in Spanish of course, that he was on the golf course when he remembered he had to teach. “You ruined a great game,” he would say.
Invariably, they would laugh, and that was just what he wanted. “A burst of laughter is like an unexpected quiz, “ he says. “It shows they understand.”
