Martha Goes to School - TD thinks it would be funny to put Martha's name on the list for substitute teachers. What started out as a joke, turns into a nightmare for Helen, Alice, and TD, when Martha gets the job and takes it very seriously. TD and the Light Bulb of Doom - TD swears he'll start working on his report just as soon as he watches the "Harry Blotter, Boy Wizard" movie marathon, all nine parts! As Helen predicted, TD winds up in a panic until he has a moment of inspiration. Can he pull off his project in time?
