I had been playing rugby with some chaps across the RAF, at a secret rotary base near London Village. The chaps from across the water were off into London for a debauched night of partying sans the threat of Paddy battering them for being RAF. I asked them what their 'cover jobs' were to be, all in the interest of being an efficient young security aware chap.
" I tell 'em I fly helicopters in the RAF " was the retort from the dashing pilot. B@$t@rd, thought I!
I did see a guy with 'Olympic Muff Diving Team' embroidered on his polo shirt tell a group of girls it was a new sport and he was under top secret military training for it. Worked too!
