"Tolfdir's Accident" is the eighteenth episode in the Skyrim for Pimps series and the fifth episode of Season 2. This episode continues the "very special kind of walkthrough" for the College of Winterhold quest-line in The Elder Scrolls V: Skyrim.
In Labyrinthian searching for the Staff of Magnus, Crotch Guzzler has fun with viewing the College of Winterhold mascot Bored Face and playing with skulls. He sees some spectral workouts and his nirnroot alert goes off in the process as well. Crotch eventually comes across a dragon priest in a big orb of magic. After defeating him, he takes the Staff of Magnus and the priest's mask as well.
While attempting to leave Labyrinthian, Crotch is stopped by a high elf named Estormo (who may be Ancano's twin brother). Estormo wants to take the Staff of Magnus, but Crotch murders him with it instead. After this, Crotch tries on the dragon priest mask he took and is satisfied it displays how bored he feels.
When he arrives back at the college, Crotch finds that the entire place is engulfed in Ancano's magic. He then "accidentally" shouts Tolfdir off of the bridge. After dropping off his load of skulls in his room, Tolfdir reappears very angry and urges Crotch to stop Ancano by displaying his fists ready to fight.
Crotch defeats Ancano and stops his evil plan from destroying the college. The member of the Psijic Order then arrives to wrap things up in the most boring way possible and takes the orb that Tolfdir had discovered. Tolfdir then names Crotch as the new Arch-Mage (aka Dean) of the college.
Upon becoming the Arch-Mage, the meets Brelyna in the dorm and instructs her to follow him. He then goes to speak with Enthir to get him to return something that he had of Onmund's. Enthir will not give back what he got from Onmund unless Crotch goes to fetch a staff for him. Crotch agrees, though he's not entirely pleased. He's not happy that being the Arch-Mage doesn't mean that everyone will listen to him and tries to jump off the side of the college and kill himself. However, Crotch lands in the water and remains unscathed.
