He was thought to be cool by most of the kids, using Facebook, Twitter and sending text messages to the kids instead of giving them actual work. He was fired after he put vodka in his Blue Bronco Energy Drink and insulted the students while drunk. He had only just gotten a Masters in education at Tufts University before he took on that fourth grade class. Ironically, Bart considered doing the exact same thing to him in an attempt to get Krabappel back before deciding instead to admit he was responsible for Krabappel's firing and take any punishment so long as she is brought back, and made clear he did not spike his drink when Skinner heard the commotion. They were his first class ever.
