It's finally time, latchkey kids! Time for a VERY SPECIAL episode about very special episodes! Remember when Mr. Drummond would occasionally open "Diff'rent Strokes" by looking straight into the camera and warning you that you were in for a VERY SERIOUS TOPIC that would not include any of Arnold's typical antics at all, and may very well leave you traumatized? Well THIS is exactly that kind of episode! Join Dr. Amy and Punky Brewster as they mourn the loss of the Space Shuttle Challenger astronauts, completely oblivious that Aaron has locked himself inside an abandoned refrigerator.
