CCF at my school, early 1970s. Parade rehearsal for inspection by GOC Norn Irn (which narrows the choices of which school!). Parade commander a RNVR Lt (ie a schoolmaster in a dark blue uniform with gold braid that had barely previously seen daylight), addressing RN contingent commander an RNR Lt. of somewhat greater age. This being rehearsal, best uniforms are not being worn by most and RN contingent commander is sporting a moth-eaten uniform jacket (with impressive amount of fruit salad) worn over an off-white seaman's poloneck.
Parade commander hollers across parade ground to RN contingent commander "You Sir! Where DID you get that uniforrm?!"
Reply: "In the Convoys, Sir; where did you get yours?"
