Explosion on a rainy day

Well, today I was involved in an explosion. It wasn't a dramatic bomb or something, much duller, and a little less cool. I was innocently expelling urine, and when finished, pressed the flush button. Now, this is not something I always do in public toilets; if a few hundred people a day push the same button within seconds of defecating or urinating, well, forgive me for not rushing to be a part of it. Anyhow, I felt it the right thing to do in this circumstance, for whatever reason.
How was I rewarded for my good deed? Putting my personal hygiene on the line for the sake of the greater good? With an exploding cistern. The pipe inside must have broken, and water was spraying up into the roof with rather profuse force. The top half of the cistern had fallen in front of the water supply tap, so i had to pick it up and shift it before turning the tap off. The tap, by the way, was turned completely on - that is about fifteen turns, when surely one or two would suffice to allow maximum water flow?
Walking back along the corridor, dripping with toilet water and in a demonstrable rage, I passed a few mates who were just coming back from the parking lot, where they had been trying to SlimJim their way into a car; and they took great delight in heading off to examine the cubicle. Well at least they were entertained; but I, still very cold, and very wet, was less so. Particularly because the fan was on.

Wow, way not to finish with a point eh?
