The new ensign was standing his first night watch on the bridge of a destroyer. 

Far out on the horizon, the USS New Jersey was conducting a night gunnery exercise. 

The ensign, seeing the flashes of light from the battleship, ran excitedly up to the signal bridge and pointed out, mistakenly, the "Morse code" coming from the other ship.

Ensign: "What are they saying?  What are they saying?"

Signalman: "Boom.  Boom."
