Cedric was our GSCE English teacher. I always thought this nickname was just childish alliteration, but the real reason soon became apparent.
During his lessons we would occasionally hear a long hissing noise, as he slowly but surely pissed himself.
He wore a catheter bag, which might explain why his pissing hissed, to be honest I never put my hand up and asked "sir, why does it make a hissing sound when you stand in front of class and piss yourself?"
Occasionally... this bag would develop a leak. And because he wore the same trousers everyday, a succession of dry salty tidemarks would develop around the crotch.
It is with a sense of shame - the man was incredibly nice - that I remember the whole class roaring with laughter. Cedric thinking it was due to his excellent depiction of Malvolio in Twelfth Night. Us, because the more we laughed, the more it encouraged him to prance about and the bigger his wet patch would grow.
(I have checked this entry out with the author, and he swears blind that it is all true. And that's good enough for me. - Log)
