In many sitcoms and teen dramas where young persons are the focus of the show, parents (and other adult authority figures) serve no purpose in the show other than to swoop in at the last second to either deliver An Aesop or to ensure that they Can't Get Away with Nuthin'.
After a while, you start to wonder how exactly they keep catching the kids, given that they seem to have absolutely no involvement in their lives otherwise.
Few shows adhere strictly to this model: in many, the adult steps out of this role on rare occasions for a A Day in the Limelight episode. Another alternative is the half Parent ex Machina; the show typically employs Two Lines, No Waiting, with separate storylines for the adults and the kids, which interact only at the last moment to deliver An Aesop or catch the kids. Many a Double Aesop is forged this way.
Essentially one step up (or down, depending on how you look at it) from Adults Are Useless. Compare and contrast Parents as People, where the parents are almost too busy getting Character Development to actually do any parenting.
- Uryuu Ishida loses his power at the end of the Soul Society arc. When he is targeted by two Aizen-designed Menos-class hollows, his father appears out of nowhere to save him. The pair have been fighting for years because Ryuuken hates quincies and didn't want Uryuu to become one, so Uryuu is shocked when Ryuuken volunteers to restore Uryuu's power to him. Although the restoration method turns out to be brutal (it can only work if the quincy is pushed to both their physical and spiritual limit), Uryuu's power is duly restored. The story still has not explained why Ryuuken offered to restore Uryuu's power despite having spent years wanting Uryuu to give up being a quincy.
- At the climax of the Arrancar Arc, the captains, Vizards and even Urahara's group have been defeated by Aizen and there's nothing Ichigo can do, leaving him powerless to watch as Aizen departs the battlefield. Cue his father miraculously gaining his feet in time to inspire him to give pursuit. Not only that, but once inside the time-warping Dangai, Isshin just so happens to have the equipment on his person required to control the time-field to allow Ichigo to engage in a special training method he just happens to know all about. And in super-condensed time, too, so three months training in the Dangai is only an hour's time in the real world. Later on in the Lost Agent arc, Isshin's activities behind the scenes is what enables Urahara to design a method that allows Ichigo to regain his shinigami power.
- In the Pein Arc, Naruto in his Unstoppable Rage almost rips Kurama's seal open but he is stopped by his father, Minato thanks to a failsafe.
- Naruto is taught by Killer B how to enter his inner world to combat Kurama, a tailed beast sealed within him. It just so happens Naruto's mother, Kushina, appears as a chakra ghost and explains to Naruto that she was the previous host of Kurama, and thus has specialized knowledge on how to subdue him, including a technique that's super-effective against the demon fox. This makes Naruto's eventual fight with Kurama much easier, as his mother steps in to restrain the fox.
- Boy Meets World, especially in its early seasons. In the later seasons, Mr. Feeney's character became a lot more substantial, but the parents were all but written out.
- Leave It to Beaver. Quite a lot, just when it looks like Wally and Beaver will get away with whatever mild infraction they've committed, some acquaintence of the parents will phone and say they happened to spot the boys doing whatever it was they shouldn't have done, and they just thought they'd call and make sure everything was OK. This can get pretty annoying, especially if the kids had already dealt with the consequences of their mistake on their own; it appears to be tacked on just to reinforce that they Can't Get Away with Nuthin'.
- Saved by the Bell: We only see any actual parents a handful of times, and Mr. Belding's only purpose in the show is to show up at an inconvenient moment to say "Hey hey hey, what is going on here?"
- Just the Ten of Us, especially in its later seasons, where Coach Lubbock's four eldest daughters replaced him as the primary focus of the show.
- Happy Days and the Cunninghams, particularly Howard.
- Gilmore Girls particularly in its later seasons, though subversion since the parent-child relationship is so often reversed.
- An episode of Star Trek: The Original Series had a variation on this. Trelane, who seemed to be a Sufficiently Advanced Alien, turned out to merely be a naughty child. His "parents" (who appeared as blobs of energy) arrived just in time to save Captain Kirk and punish their boy.
- Buffy the Vampire Slayer:
- A similar situation happened in the episode about Buffy's roommate from Hell. The girl, as it turned out, was a demon who "snuck out" to spend time with the mortals. Her father "rescues" Buffy from having to interact with her anymore, at which point, Buffy moves in with Willow. Being dragged back to her dimension, the demon grumbles: "When will you stop treating me like I'm nine-hundred?"
- Buffy herself often faced this trope in the early episodes. Her mother was involved in some plots, but very few, and she almost never did anything useful. Often, when she did appear, it was to try to have a heart-to-heart with her wayward daughter about either mundane matters that had no real importance compared to what Buffy was dealing with (although usually it was somehow metaphorically related to the plot), or supernatural events that she grossly misinterpreted. Later, Buffy told her mother that she was the Slayer, which, after the initial shock, improved their relationship significantly.
- Most parents in GoAnimate Grounded videos are this; often only showing up out of nowhere to punish and ground the main character of the video once they step out of line if they weren't already present.
- Kim Possible.
- Kim's parents are at times very supportive of their globetrotting, crimefighting daughter.
- Spoofed in South Park, which usually has one of the children delivering the Aesop to the adults.
- In many episodes of Rugrats, probably a majority, Adults Are Useless from start to finish. But there are also many episodes where the parents will suddenly catch onto the Devil in Plain Sight misbehavior of Angelica, or otherwise do something useful to resolve the plot at the end of the episode.
