Whilst in boarding school down in Easy Sussex, me and a few mates thought it would be funny to use gone off fish that someone had caught in the cuckmere river and left in the fridge for weeks in some sort of prank. We lived in a boarding house that had a house master, which was the schools chemistry teacher. One Sunday, we broke into his bedroom and ripped up the floorboards under his radiator and placed the fish there. To say it stunk was an understatement, the whole house reeked heavily of fish to the point where it hit your gag reflex when you stood near his room. However, we were totally unaware of the fact that he had been in an unfortunate accident years before involving a bunsen burner and had burnt his nasal receptors which in turn affected his sense of smell, to the point where he didn't have any. A week went passed and the cleaner came in to go over the place, on walking into his room, she was physically sick. It was reported to the school and the whole house was condemned until the source of the smell was found. The ripped up all the floorboards and found the culprit fish, they instantly knew it was me and my mates who did it and they interrogated us one by one until one of us confessed. Using the old, tell us who did it and you'll only be suspended, whereas everyone else involved would be expelled. My so called good mate bubbled me up and I was expelled for it.
