A Teacher's Lot is not a happy one...
Teachers do not have to put up with much, you know. Well, apart from Headteachers, Government School Inspectors, politicians changing the curriculum whenever there is an 'R' in the month and the parents. Compared to teaching the Craft to the new recruits to the Dark Coven and Caer Surdin, it's easy-peasy.
The Grey Mage - Dark Lord of Keswick - has been promised an upgrade to his ageing and dragon damaged Mercedes if he can set up a properly managed and effective In Service Training regime for up and coming Dark Wizards. After all he's had practice with breeding all those Rabbits of Doom and being married to Poison Ivy for twenty years.
An army of trainee wizards: it worked for that Harry Potter, didn't it? So why can't The Grey Mage put his students to good use and finally conquer the Helvyndelve?
"He who laughs last thinks slowest"
"Who puts a 'Warranty Invalid if Opened' sticker INSIDE the computer casing?"
"Why have you got a bandage around your neck, Boss?"
"I've just had to interview a Vampire."
"How do you plan to deal with this problem?"
"I plan to delegate it to you, and go on holiday."
So lots of the gags are written, now it just needs the author to get on with the job...
