You rang, M'lud?
My favourite was not anonymous, but happened on a Sunday(!) at Benbecula (normally RAF Sleepy Hollow) after the Andrew cancelled our Atlantic exercise just after the tanker, so our 4 ship split for a general Western Isles wazzex for a couple of hours.
We called Benny up for a "low approach"
, apparently shortly after another of our formation had just done the same.
Just as we departed, ATC called (without callsign)
"That was bloody brilliant! And you just drowned out the Station Commander telephoning to complain about the last one!"
