"Lights Out"

A destroyer pulled into Borneo for liberty. Cut down to a skeleton watch, most of the ship was empty for the night. A few piers down, a ship was loading local cargo for export. Among the crates was an orangutan, who broke out of his cage. The ape traveled the waterfront in the dark, and finally reached the destroyer. He climbed the mooring lines, boarded, and climbed up the smokestack. Inside the stack, the confused animal made it down to the engine room, and started wandering around. He came to an electrical panel, opened for maintenance, ignored the safety ropes, and managed to make contact with an extremely high voltage contact. Bright blue spark and the ship is suddenly dark throughout.

A few minutes later, two hull techs are searching with their flashlights for the problem. They come on the dark burnt hairy body. They shine the flashlight on his long, long arms. They look at each other. They look at his short stubby legs. They look at each other. They look at his face for a long time.

Finally, the third class tells the seaman…

"Okay, his legs are too short for a machinist mate, his arms are too long for a boiler tech, and he's too hairy for an electrician. Call the wardroom, see if any of the junior officers are missing."
