My favourite patch 'dit' occurred when we were playing with the Crabs in Deci. 74 Sqn were down there and had 'acquired' a sheep/goat (we never really did establish exactly what it was), which was kept out the back of the Ops building. He was given the name, Norman. He even had his own song created; Norman biriani. The lyrics weren't great but seemed to get funnier as the evenings went by and the Deci Red levels reduced. Anyway, for those who don't know, 74 Sqn's motto used to be (is.....I haven't a clue) "I Fear No Man". I thought the insertion of an 'R' on all the squadron patches was really quite funny and still have, somewhere about the house, a 74 Sqn patch with "I Fear Norman".
I know, I should get out out more but, for the Junior Service, I thought it amusing
(PS: Norman was eventually released back into the field from whence he came, to re-join all the other shoats/geep/whatever they were and probably lived happily ever after for the next week or so).
