S4, E7: Guest Monkey: George is almost as excited as Allie on her first day of school, but is ecstatic when she invites him to school the next day as a special guest monkey! He soon learns, though, that kindergarten has a lot of special rules that he's not used to - like not climbing on the furniture or standing in the sand table. Will George get extra credit for trying to follow the rules, or will his effort create one big mess? Charkie Goes to School: Charkie's building has a new rule - all dogs must have a good-behavior diploma from obedience school. After seeing Charkie struggle with the obstacle course, George recruits the academy's top alumni, Hundley, to help prepare Charkie for the final exam. Can George and Hundley figure out a way to get Charkie to cross the finish line amid all the distractions?
