Goatly
A student wizard and contemporary of Barnsforth in the Department of Post-Mortem Communications encountered in Making Money. He chose his degree option on the grounds that the hooded all-black robes and the skull ring would make him a "babe magnet". It can therefore be deduced that either the sort of babes he wishes to attract will require a shovel as part of any wooing strategy, or that Necromancy, whoops, Post-Mortem Communications, attracts student wizards (and presumably groupies) of a certain Gothic turn of mind and dress.
Despite only having turned in two-thirds of an essay all term, and that as part of a group effort, his graduation as a Doctor of Post-Mortem Communications, with straight A's and skull ring, is virtually assured. This is after Barnsforth chose the occasion of a stealth Insorcism on Professor Flead's immortal spirit as an opportunity to discuss the ethics of Insorcism with their tutor, Professor John Hicks, who is morally and professionally bound to set the concerns of his students at rest concerning the morality of a practice which Mustrum Ridcully and the College Council has emphatically banned. Hicks is forced to concede Doctorates all round in order to ensure the professional discretion of his students concerning this, and indeed any future practice of, Insorcism.
