Just found this thread and have been reading it off and on all day.
Funniest thing I ever heard was four or five years ago at an air show at Hanscom AFB in Massachusetts. (I may have some of the details wrong - was a while ago). Then Secretary of the Air Force Sheila Widnall was in attendance, in the VIP area. (Side note - my wife used to babysit for her kids, when she was Professor Widnall and we were students at MIT). Anyhoo, there was a B1 fly-by, and I was listening to ground-to-air comms. A high-speed, high-level pass, then a couple of low-and-slows back and forth along the runway in front of the spectators. The following comms (roughly) ensued:
B1: Hanscom, Air Force 123 returning to base.
Hanscom: AF 123, request you make another low-level pass.
B1: Negative, RTB.
Hanscom: Strongly suggest you make another pass.
B1: Negative, we've completed the program, RTB.
Hanscom: The Secretary of the Air Force requests that you make another pass.
B1: Air force 123 making a left 180 for another pass over the runway.
