I don’t think I’ve ever seen anything like that before, even here! :-O
In WWII, SS officer `Panzer’ Meyer once used an unusal method of getting some troops to move.
They were bracketed and wouldn’t budge. He pulled the pin on a grenade & set it down next to them, then showed them the way. They followed quickly.
Lay some tear gas canisters next to these pin-heads and they’ll move too.
