An Air Force cargo plane was preparing for

departure from Thule Air Base in Greenland. They were waiting for the

truck to arrive to pump out the aircraft’s sewage holding
tank.
The Aircraft Commander was in a hurry, the truck was late in arriving,

and the Airman performing the job was extremely slow in getting the

tank pumped out.
When the commander berated the Airman for his
slowness and promised
punishment, the Airman responded: “Sir, I have
no stripes, it is 20 below
zero, I’m stationed in Greenland, and I
am pumping sewage out of
airplanes. Just what are you going to do
to punish me?”
