->''"Empires are always destroyed from within. And I can prove it to you from the comparative comfort of this tacky chair. I will give an A to the one person who unties me. The rest of you will get an F."''
-->--'''Professor Cornwalis'''

Annie invites Professor Cornwallis (Creator/MalcolmMcDowell) (and Kevin) to the study group's Christmas party at Jeff's apartment to make up for their failing grade on their history assignment. After many failed attempts of ass-kissing, the group finds out that their supposed F was actually a C-; Annie wanted to the group to go for an A. When Cornwalis overhears Jeff's conversation, their grades brought it back down to an F. While the study group is distracted and arguing, Kevin ties up the professor in an attempt to prove himself, leading to a series of mind games and bribes as Cornwalis tries to prise the group apart.
