Plot

Michael is a guest speaker for Ryan's business class, but they have a falling out after Michael finds out that Ryan spoke negatively about Dunder Mifflin. Back at the office, Dwight tries to kill a bat that he found in the ceiling.

When asked by Ryan to be a guest speaker at his business school, Michael is honored and is very excited. But while there, a very rude remark about Dunder Mifflin makes Michael mad and he takes it out on the class and Ryan. Meanwhile, Dwight finds a bat in the office and tries to solve the problem. Jim tricks Dwight into thinking he is turning into a vampire.—James Hake
