When I was at Ames Research Center, on Moffet Field NAS (working on aircraft for NASA) there was a sign in the main hanger which said, "Never Taxi an Aircraft Faster Than a Marine Can Think."
We used to use "Army Spec" when tightening bolts on the aircraft: "tighten it till it strips and then back it off a 1/4 turn."
and the Marines all called the Navy airmen "squids" because they were "just a lower form of Marine life..."
There were all branches of the services in that one hanger, and it got fun sometimes.
