When you are in Grade School or even High School most students are excited at the prospect of a substitute teacher, but when you are in College and are actually paying for classes, a sub pretending to be a professor may not be the best situation.I love this video for so many reasons, everyone is trying to be attentive even while his list of demands gets more insane, plus how he tries to intimidate everyone out of the gate. Watch for the guy taking notes even righting the professors name down in his notes. Classic :)
