When I worked with kids in the UK we had a similar call.
But for us it was 'assume the position!'. the kids had to find the nearest wall and stand with their legs apart, hands on the wall facing the wall and not talking until we told them they could move.
Often the last one to comply was thrown into the lake. (until they figured this out and they all tried to be the last one)
I don't work with kids any more..... ;-)
I wonder if it would work on wives?
LOL!
No. It doesn't :-( hehe
Worth a thought. maybe if you had Dolphins in the area?
