Practical joke

I attended a girls high school.  One of my childish jokes was to go in to the toilet and lock the door then climb up onto the cistern and then step over to the next toilet and lock that door and so on until the last toilet where I let myself out.  As you can imagine a school full of girls means a school full of girls wanting to use the toilets.  I never really stayed around to see the mayhem for myself but sometimes stood outside listening to raised voices.  This of course was bad enough but I also did the same thing with the downstairs toilets.  I thought it was hysterical.  It was a juvenile joke but hey, I was a juvenile.  If anyone reads this and remembers being a victim of this so-called joke, I am glad that you do not know who is writing this blog.  Luckily, I am too old now to do the same thing in public toilets and also I don't think it is as funny as I used to.
