I remember two of my supply teachers I had... never found out their actual names, only their nicknames - not that they were ever called those to their face...
One of them was one of those stick insect like old men, complete with a little goatee beard. He refused to let anyone do anything until he knew everything about it. He got nicknames Archimedes, completly by accident too.
The other one was called Eco-Warrior.... she used to turn everything off if it wasn't used for more than 5 seconds, and we all hated her... but also liked her because one chance comment at the right time meant that no work got done because she'd end up in a discussion on the finer points of a 'Green' society...
