During an arctic training exercise in Alaska, intense cold was playing havoc with vehicles and equipment. One harassed commander was trying to cope with vehicles that wouldn't run and machinery that wouldn't work. He was wondering what else could go wrong, when the door opened and a soldier rushed in and announced, "Hey, captain, the Northern Lights are out!"
Exasperated, and without looking, the captain barked to him, "Well, go get the generator mechanic and have him fix 'em!"
