Evenin' all, just came back from a quick trip up to Reading to find my room mates have broken into my room and covered the whole lot in tin foil. Funny as it was, I need sweet sweet revenge. The only problem is, I can't think of much to do. The only applicable ones i could think of revolved around eggs and flour or a Paintball gun. Can anyone think of some decent pranks to play on them? It'll be hard to get into their rooms.
