Heh, my junior high was amazing, because the janitor puts a sign on the door to the attic labeled "Pool" for the first few weeks every year, so 8th and 9th graders tell the 7th graders that there's a pool on the 3rd floor, and they, if they can get the key from the janitors, unlock and open the attic door labeled Pool, and show them the stairs and whatnot. Last year they locked a kid in there who ran up to the "pool."
