I was told the French Foreign Legion played an interesting game called The Sheep; a variation of Are You There Moriarty.
The person to be the sheep is established by drawing straws and he leaves the room.
The anti-room is then completely darkened and everyone else stands around the perimeter of the room.
On command the Sheep enters and silently chooses what he hopes will be a good position, he then says "Baaa", and everyone fires their pistols at where they think the noise came from
