Well, harmless pranks are fun, anyway. And that's just what I and two of my roommates have just done to a third. On something of a whim, we took several large newspapers and completely covered this other roomy's room. First the floors were papered, then we got more creative... I started shoving crumpled paper into random items and pieces of clothing. He'll be finding newspaper in places for months, if not years. One of my roomies put crumpled paper underneath his bed's cover sheet, put the covers back on, then we covered the covers in paper. He also took the pillows out of their cases and filled the cases with newspaper. For a coup de gras, we wallpapered most all of his walls, making sure to tape each sheet individually so they cannot be torn down all at once. We also severely taped up a few sheets; each one will take forever to remove. Finally, we put a long line of tape from the top crack of his door, down to the floor, around the corner, out the front door, across the porch, and halfway down the walk. Something for our roommate to follow, if you will. Heh heh heh.
