I understand that a certain ex-Lightning pilot was nicknamed 'Doof' for the rest of his career after a game of mess rugby during flying trg. I do know the chap concerned but apologise for re-telling his story....Apparently, 'Doof' was the noise that his fist made when it connected with the nose of a very senior officer during a game played in the Valley Mess. Young Doof had not realised who owned the nose, or indeed how senior the nose's owner was, and he was merely intent on earning retribution against an over-zealous opponent. The senior officer shrugged it off under the heading of, 'There but for the grace of God go I'.
