When I reported to aviation training school we had to undergo a flight physical. We were all standing there in the nude when the Doctor entered the room. He told us that we were to undergo a short arm inspection as a part of the physical. He told us to “Skinner back and milk it down”. One of the guys in the group told the Doctor to smile at it and it would fly back. He failed his physical.
Later we had to take an aptitude test and one of the questions was to draw a pendulum. One of the men drew a Penguin. He too failed the test.
As Forrest Gump would say, “Stupid is as stupid does”.
