As my supervisor and I were leaving the headquarters building at Hickam AFB, Hawaii, the lawn sprinklers, which had been showering the walkway, stopped suddenly.
Realizing that he had forgotten something, my supervisor went back inside, and I followed him. With that, the sprinklers started again. We surmised that there must have been a motion sensor controlling the spray, and decided to test it by walking back and forth and in and out the front door.
After several attempts at fooling the system, I began looking around for the sensor. By the side of the building I saw a very confused gardener, his hand on a water faucet.
