A really good one is to get some "gaffa" tape & peel a long strand off the edge (about as thick as a piece of cotton), then stick it to the side of a car, preferably a dark car. From a distance it looks like the car has a massive scratch on it. hahaha.
Once in my army time, one of the guys who we didn't like too much had been out on the p*ss. He stumbled into the room & colapsed on his bed, about half an hour later 8 of us carried him (still in his bed) up to the washrooms on the next floor. The lads in the troop upstairs thought that this was hilarious, & the next morning crept around whilst washing & shaving so not to wake him. Needless to say, he was late for parade & had a hell of a time explaining to the sargeant major.
