The School of Janitorial Science is headed by retired psychopath Voldemort, formerly Lord.
His prominence in FATS counsels may be judged from the following transcript of a faculty meeting:
"Mr. Voldemort, you're late to the meeting again!"
"Sorry, Mr. Morambar, I was defeated and humiliated by a little boy on my way here. AGAIN."
"And do you think you could dye your eyes? Red is SO middle-management. And also somebody found yet another Horcrux in the campus dressing rooms. Could you PLEASE take better care of them? One dosn't just leave those things lying around."
Sadly, Dr. Voldemort is always in financial trouble because, owing to New Line Cinema's perfidy in refusing to pay MORAMBAR what he is owed, FATS is unable to fund his department as much as it would wish. Some of the ruder students nickname him Voldemortgage, which seems a bit unfair. But Voldemort's department wouldn't be broke if he knew how to write a grant request.
Voldemort doesn't get out much or have much fun, since being Voldemort hardly does wonders for one's sex life.
Core courses include: Theory of Sweeping, Theory of Mopping, Concept of Cleanliness, Care of Horcruxes. The student's final grade will be determined by how well he or she cleans the Orkish restroom of the opposite sex.
