A quick true story. In my early 20's I worked in a tax accountants. One of our best customers who contacted us almost daily, went quiet for a couple of months which was unlike him. We eventually got a letter from him with a photo of him in a wheelchair with a broken arm and leg.
He had been having a sneaky fag on the throne and when finished put it between his legs into the bowl and that was about the last he remembered before waking up in hospital. Seemingly his wife was frightened of spiders, and had brushed one into the toilet bowl and for whatever reason decided to pour a whole tin of lighter fluid on top of it
Our customer had severe burns to his rear end and a broken leg as he landed on the edge of the bath surrounded by the remains of the bowl. When the ambulancemen were carrying him down the stairs they were not concentrating (they may have been laughing) and they dropped the stretcher which caused his broken arm !! The story later appeared in in book of strange accidents as the local paper got the story (he never forgave his wife either), but it was absolutely true.
