I worked with a Cpl (Dick I) while on Chinooks and he managed to stop the whole room and had everyone aghast with the line... "when I was on Sunderlands"
Mind you Taff Walkers line on the Station open day when he espied a Mk19 Spit, "When I last saw one of those it was on the classified list and I couldn't get near it" was a hard one to beat.
Also met a couple of Aerial erectors out in Germany sharing transit accomodation, even then they were a dying trade, as were the painters and dopers and the station chippies.
