* {{You are Grounded}}: This episode marks a major turning point in the franchise's history as for the first time in the series' history, we actually see a character get grounded. In this case, Bart Simpson. Now while Bart had been grounded in the comic book series, (read "When Bongo's Collide" to see one of the earliest groundings in the franchise's history), and while there have been references towards the grounding itself (especially between Seasons 20 and 21 in episodes like "The Good, the Sad, and the Drugly"), this marks the first time a grounding featured in the series became canon, and was not largely ignored, ("Marge Be Not Proud") or used as part of a joke ("Fraudcast News"). In fact this episode not just marks a first for having an actual grounding be used as a serious part of the story, but features many of the tropes and cliches that most "Token Grounding Episodes" have, including having a sibling (mainly female) relish with delight over their relation's grounding, (Lisa), a "No TV!" reference (said by Homer), a character making a pointing down gesture as they tell their child that they are grounded, (performed by Marge), and the mother being the one who tells the child he or she is grounded, (Marge again). This marks one of the most pivotal moments in the show's history because they have never had an actual grounding occur in the entire series, not even during the original shorts from the late 80's. Usually a child character would be sent to their rooms or punished in other ways. ("Itchy and Scratchy: The Movie" and "Double, Double, Boy in Trouble" are notable examples of this trope, with the latter being a final bow for the old non-grounding system of discipline)
