Oops..
Wildenrath circa 1990. Radar bay subject to brand new OC Eng's inspection (nobody from the bay had met or seen him). Bay entrance was locked (phantom radar secret spec). Anyway cue knock on the door, bay personnel prepared, blah. Door opened by a certain Welsh Flight Sergeant who was confronted by the usual flunkeys and hangers on and aforementioned brand new OC Eng who was (and is) a gentleman and also black as the ace of spades. In the split second of opening the door and processing what his eyes could see but not necessarily thinking before speaking, his salutation was "Howdy Doody Sir", to which, without batting an eyelid, the reply was "Howdy Doody Flight Sergeant". Top reply and a top bloke.
