When asked by Ryan to be a guest speaker at his business school, Michael is honored and is very excited about it. 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 all while Jim tricks Dwight into thinking he is turning into a vampire. Written by James Hake
Good insights into business, and the way Michael thinks, while staying funny as ever. Jim's prank on Dwight is one of his best!
