I can't even recall which...
... school this was. Probably in Leighton Buzzard (The Cedars).

I put a condom on the external door handle, and our geography teacher (a newly-graduated pretty, young thing) wouldn't touch it, so we got the lesson for free.

Then there was a chat I had with the about-to-retire female English teacher, mother to one of our classmates, as out of the corner of one eye I could see the water-filled condom sitting on top of the credenza. It was enormous, like a beached beluga whale. The way it rippled and seemed to breathe was fascinating, and I couldn't take my eyes off it. Of course she noticed, but was a jolly good sport about it, asking me who had done it, with a twinkle in her eye and a smile on her lips. I told her I had no idea, but secretly wanted to confess that I had filled it and was about to drop it out of the window onto the head of an arsehole.

Condoms are fun, kiddies!
