Not my own game, and can't say I have tried it but it made me laugh. In a book by an ex Army Officer, the game is called "bicycle races".
Two contestants; CONTESTANT 'A' has to run to a bicycle on the mess lawn, don a large leather greatcoat and cycle helmet, hop on a bike and ride like hell to the finish line.
CONTESTANT 'B' has to run to a dis-assembled shotgun, re-assemble it, load it with some cartridges (loaded with rice instead of lead shot), and try and shoot the cyclist before he reaches the finish line.
Apparently the cyclist usually won, until someone discovered not all of the parts of the shotgun were needed to fire it, providing it was loaded before the barrel was put on (therefore cutting assembly time in half). Ended with contestant 'A' off to the med centre to get rice picked out of legs and back.
Good luck trying that in this day and age...
