"Business School" is the seventeenth episode of the third season of the American version of The Office and the show's 45th overall. In the episode, Michael Scott (Steve Carell) is invited by Ryan Howard (B. J. Novak) to speak to his business school class. When many of the students question the usefulness of paper in a computerized world, Michael attempts to inform the class of how essential paper is. Meanwhile, a bat becomes trapped in the office, leading Dwight Schrute (Rainn Wilson) on a mission to protect the employees.

The episode was written by Brent Forrester and directed by Buffy the Vampire Slayer and Firefly creator Joss Whedon. Whedon became involved with the show due to being a friend of series creator Greg Daniels as well as series co-star Jenna Fischer. Despite Whedon's experience with Buffy the Vampire Slayer, the subplot about Dwight coming to believe that Jim Halpert is a vampire was entirely coincidental.

Plot

Ryan Howard (B. J. Novak) invites Michael Scott (Steve Carell) to speak at his business-school class. Michael is excited, but Ryan admits in a talking head interview that he has only invited Michael because his professor promised to bump up the grade of any student who brings their boss into class. During his introduction of Michael, Ryan predicts that Dunder Mifflin will become obsolete within five to ten years. However, Michael could not hear him and proceeds to ruin the event with his antics (including tearing pages out of a student's textbook to prove you "can't learn from textbooks"). One of Ryan's classmates asks for Michael's opinion of Ryan's prediction, which Michael only just learns about. Infuriated and hurt, Michael rants about how Ryan has not made a sale before punishing him by relocating his desk to the "annex," where Kelly Kapoor (Mindy Kaling) works. Kelly babbles uncontrollably in excitement at the news.

Meanwhile, Dwight Schrute (Rainn Wilson) discovers a bat in the ceiling. It flies through the office, sending the employees scurrying for cover. Jim Halpert (John Krasinski) and Karen Filippelli (Rashida Jones) exploit Dwight's paranoia, and pretend that Jim was bitten by the bat and is turning into a vampire. Jim calls animal control, but Dwight insists on catching the bat himself even after 5 p.m. passes and the other employees go home, except Meredith (Kate Flannery), who continues to hide in the breakroom for fear of the bat. Dwight eventually catches the bat with a garbage bag after it lands on Meredith's head.

Pam Beesly (Jenna Fischer), in the meantime, invites her co-workers to her art show after work. At the show, Oscar Martinez (Oscar Nunez) and his partner Gil (Tom Chick) critique her art, with Gil dismissing it as "motel art," not realizing that she is standing right behind them. None of her other co-workers show, leaving her feeling alienated and sad. Roy comes by and compliments her work, but obviously does so as a "boyfriend's gesture" with no sincere appreciation for art. The general attendees show little interest in her drawings, and she begins to doubt her abilities. As she begins to take her work down, Michael arrives, having been delayed by the trip back to the office to move Ryan's things. He expresses sincere awe for her work and asks to buy her drawing of the office building, saying that he is very proud of her. Pam embraces him as her eyes tear up. Michael hangs Pam's drawing on the wall next to his office.
