A friend of mine with the RM served with the USMC on exchange in Beirut in 1983. Luckily, he left just before the big bomb that killed a few hundred of the poor buggers. Anyways, as many of you may know, the yanks are fond of putting up big signs that say things like '137rd Underground Balloon Maintenance Platoon - Second to None!'.
So he had a T-Shirt made up for himself that he wore around the base. On the front it said, in large letters, 'None'.
They didn't get it.
This had apparently been done before by British or Canadian troops in Korea, but I can't find the reference so it may be an Urb-Leg.
