If it's anything like the CCF when I was at school (probably not) you'd be boobytrapping the door of whatever premises you use to keep adults out while you got revoltingly drunk, causing mysterious explosions in the shrubbery, and making NCO's go ballistic at regular intervals. The best story was the one about the trip to an army camp in Germany. The sergeant lined them up and asked for their names.
'Cock, Sir.
'Crutch, Sir.'
'Stiff, Sir.'
At this point he hit the roof. It took a teacher armed with the official list of names to convince him that they were real.
