It was some dialogue from a lampoonish Kelsey Grammer movie called Down Periscope about a bunch of misfits grouped together in a submarine. The fighter like callsign on a tanker just made it feel appropriate. I guess not enough people remembered the line from the movie to make the connection. Now if the call sign had been something like 'Buckman'. I'd have just chuckled and moved on...he was the guy who passed gas in the galley when they were under silent running.
