April is Edna Krabappel month on the show! For the next few weeks, Irvin and Nacho are celebrating Bart's beleaguered 4th grade teacher at Springfield Elementary with some of her best episodes, and this one is a great one. We cover the sordid details of Bart's redemptive game of deception with his teacher, and also spend some time talking about yo-yos, Mrs. Krabappel and Nelson having the same catchphrase, and one of the best no-brainer Simpsons crossovers that hasn't happened yet.
