Peg discovers that she never graduated High School, because she flunked one class: home economics. Now she must go back to school with Kelly and pass the final exam. This results in some problems for Kelly. [Note: Buck talks for the first time. Peggy is sitting on the couch, asking: "What channel is 'Wheel of Fortune' on?" Buck answers: "Uhh, it's seven, just like yesterday and the day before".]
