The pineapple is part of PRIATE's initiation: to get in, you have to pick up a pineapple (with your buttcheeks or eyelids; your choice) and drop it into a volcano while several carniverous monkeys claw their way into your nostrils.
Oh, and funny you should mention needing more public bathrooms - my high school locks several of our bathrooms for reasons I have not been told. in one case I needed to use the warm-air-blowers they have to try your hands, but I needed it to quickly dry some paint on a piece of artwork, so I went to one bathroom, which was locked. The second was also locked. The third was open, but didn't have hand-blowers, it just had paper towels.
