The Bursar
Background
The Bursar is a wizard at the Unseen University in Ankh-Morpork, on Discworld.
During the events of Terry Pratchett's Hogfather (2006) played by Roger Frost
Ponder Stibbons tells The Bursar that they no longer have a radiation shield as Hex advised it was needed. Ponder then shows The Bursar a thaumic particle accelerator the students built. The Bursar runs to The Dean and asks him if he has seen the Head of Inadvisably Applied Magic. The Chair of Indefinite Studies suggests he ask the Lecturer in Recent Runes and an explosion erupts. Mustrum Ridcully walks into the room and says in his day as a student he wouldn't be studying the night before Hogswatch. He tells tells The Bursar and the others that he is going to reopen former Archchancellor Weatherwax's old bathroom. Modo gets the machine ready for Ridcully to take a shower, and The Bursar and others warn Ridcully against using the shower, but Ridcully gets into the shower. Ridcully turns a tap called Old Faithful and then quickly exits the shower due to the extreme water pressure.
Susan brings Bilious to the Tower of Art of the Unseen University for Wizards and asks Ridcully for help. The Lecturer in Recent Runes tells Susan he can cast a spell that can take away Bilious' hangover and separate it into a vial, but might kill him. The Dean suggests they just mix up everything and give it to Bilius. Bilius tries the concoction and survives. Ridcully tells the other wizards that he had mentioned a god of hangovers and the Lecturer in Recent Runes says at least he didn't say anything about a Hair Loss Fairy. They go to Ponder Stibbons to ask Hex for help. Ridcully asks Hex about what is going on and while they are waiting, a Hair Loss Fairy appears on the head of The Dean.
Susan thinks Ridcully is calling beings into existence and The Bursar mentions he wondered if there was an Eater of Socks. A drunk Student Wizard walks into the room wearing a Toothguard helmet and then passes out. Ridcully asks Hex where the Tooth Fairy's castle is located at. In the laundry room, the Eater of Socks eats one of the Chair of Indefinite Studies' socks. Ridcully asks Hex again what is going on and Stibbons tells him he thinks what they are getting are personification of forces. Hex says new creatures are appearing due to some beliefs disappearing. The wizards stay up to catch the Hogfather as he delivers presents. Death shows up and they catch him and notice he has a fake beard and pillow under his robe. Death tells the wizards about the Auditors and their plan.
