There was the RAF Canberra pilot on detachment as liaison during a land/air exercise at Sennelager in the 60s who, at breakfast in the tent, fell foul of an old (supposed) Army tradition.
Being ignored by the only other person at the table when he asked for the marmalade to be passed, he repeated his request louder. Still ignored, he asked again LOUDER!
The Army officer, now clearly irritated, then responded with: 'Don't you know that when an Army officer wears his hat to breakfast he does not wish to be spoken to!
The RAF Officer, somewhat taken aback, raised his Size 10 Flying boots from the floor, planted one of them firmly in the Army chap's Corn Flakes and said: 'And when a Canberra pilot puts his boot in your Corn Flakes it means PASS THE F*CKING MARMALADE!
Apochryphal - Probably!
Worth telling - Perhaps!
