"You must be full of crap!" joke
A US Air Force C-141 is scheduled to leave Thule Air Base, Greenland at midnight. During the pilot's preflight check he discovers that the latrine holding tank is still full from the last flight. So, a message is sent to the base, and an airman who was off duty is called out to take care of it. He finally gets to the air base only to find that the latrine pump has been left outdoors and is frozen solid so he must find another one in the hangar, which takes even more time. He finally arrives at the aircraft and is less than enthusiastic about what he has to do. Nevertheless, he goes about the pumping job deliberately and carefully (and slowly) so as to not risk criticism later. As he's leaving the plane, the pilot, an Air Force Major, stops him and says, "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." The poor guy says, "Sir, with all due respect, I'm not your son. I'm an Enlisted Airman in the United States Air Force. I have one stripe, it's two thirty in the morning, it's twenty degrees below zero and my specialty here is to pump crap from an aircraft. Now just what form of punishment did you have in mind?"
