There is nothing funny about surgery; that is, of course, unless you line a person’s insides with a touch sensitive metal circuit and fill them with ridiculous items like a broken heart, a pencil, or butterflies. Hilarity ensues as each participant tries to remove real, non-fatal conditions, such as water on the knee, brain freeze, and a charley horse. Operation succeeds in turning an experience as frightening as surgery into a game worthy of outbursts of laughter and silliness. Operation was designed in 1964 by University of Illinois industrial design student, John Spinello. While the game tests hand-eye coordination, it also shows that something as serious as surgery can be a joyous good time.
