I remember crewmembers on my sub mooning the USS Eagle (the Coast Guard Barque i.e., sailing ship) as we went east and they went west through the Panama Canal in the late 70’s.
But then that is what bubbleheads do...
When I was on the JFK one time, my plane was parked right at the edge of the ramp...there was a Soviet trawler behind us, and there were a bunch of guys looking at us with binoculars. Looked like a row of bugs on the bridge..my buddy and I just pulled down our pants and mooned em...:)
They didn’t budge a bit, from where I could see, it had no effect. I often thought it would have been funny to see and hear them. I could just imagine one of those guys elbowing a guy next to him and saying “Hey! Look at this...the Ameranskis are baring their asses at us!” Such is the tedium of being away from home...
