A US Air Force C-141 was scheduled to leave Thule Air Base, Greenland at midnight. During the pilot's preflight check, he discovered that the aircraft's latrine holding tank was still full from the last flight. So a message was sent to the base, and an airman who was off duty is called out to take care of it.
The young man finally got to the air base and made his way to the aircraft, only to find that the latrine pump truck had been left outdoors and was frozen solid, so he had to find another one in the hangar, which takes even more time. He returned to the aircraft and was less than enthusiastic about what he had to do. Nevertheless, he went about the pumping job deliberately and carefully (and slowly) so as to not risk criticism later.
As he's left the plane, the pilot stopped him and said, "Son, your attitude and performance has caused this flight to be late, and I'm going to personally see to it that you are not just reprimanded, but punished."
Shivering in the cold, his task finished, the airman took a deep breath, stood up tall and said, "Sir, with all due respect, I'm not your son; I'm an Airman in the United States Air Force. I've been in Thule, Greenland for 11 months without any leave, and the reindeer are beginning to look pretty good to me. I have one stripe, it's two-thirty in the morning, the temperature is 40 degrees below zero and my job here is to pump sh*t from your aircraft. Now just exactly what form of punishment did you have in mind?"
