HuwG, I know what you mean by senior NCO sense of humour. We did get our own back on a BSM at the last battery parade which he presided over before his retirement. Every body on parade in best black belt and brass order, dress "polys" with slouch hats. Drilled to perfection and every order beautiffully exectuted. He watched us for twenty minutes before he realised that every single hat was on backwards, with turned up brim on the wrong side........

Such language........
