Rod and one of his fellow soldiers were assigned to wax the floors of their barracks. They'd heard that if they got the wax really hot, it would just glide across the floor, cutting their labor time in half. Unfortunately, as they were heating the can of wax with a cigarette lighter, it caught on fire, setting off alarms and attracting firetrucks, ambulances and the police.

Rod had to report to his sergeant's office immediately. Assuming he was in big trouble, he took a deep breath as he faced his superior. But before Rod could say a word, the sergeant simply muttered,

"Been there, done that.

You're free to go."
