A certain RAF Loadmaster was working down the back of a C130. An Army Major called "I say, Staff....STAFF!"
The Loadie ignored him.
"STAFF...STAFF! I'm talking to YOU!"
Loadie says: "Oh, do you mean me, sir? I'm a Flight Sergeant, not a Staff Sergeant..."
Major: "Well, Flight Sergeant, if you were in the army, you'd be a Staff Sergeant!"
Loadie: "If I was in the Army, sir, I'd be a Brigadier!"
