Kids Shouldn't Watch Horror Films
Alice and Bob are two mischievous little kids aged around 8-14. One day, they decide they'll go to the movies. Their parents are fine with this, but warn the two of them not to see that new horror film that just came out. Alice and Bob swear they'll see an age appropriate kid film and go off to the movies innocently. Of course, they'll go see the horror film anyway, either getting in easily or sneaking in if the guy at the ticket booth won't let a pair of kids in. This backfires when they find out how terrifying and gruesome the horror movie is, and nearly end up half-traumatized. The rest of the episode will usually consist of them having nightmares and eventually being outed to the parents at seeing the film. Another common version is the kids watching it at home when the parents are out. Sometimes, though less common, the parents will be there as well.
Of course, in Real Life, a lot of children enjoy a good horror movie. At least depending on their age.
If this trope pops up in a kids' sitcom, it will almost always overlap with Can't Get Away with Nuthin'. See also Girls Are Really Scared of Horror Movies and Scare'Em Straight. When something like this happens in Real Life, see What Do You Mean It's Not for Kids?. It can sometimes be inverted, where adults are terrified of the film but kids love it. (See also Fridge Horror for that case; perhaps the kids don't understand why the events of the movie are something to be afraid of.)
- In the first Home Alone movie, Kevin watches an old gangster movie that he was previously not allowed to see. It ends up scaring him, but he later uses the audio of that scene to ward off the burglars (as well as to scare the living daylights out of a pizza deliveryman). He watches another in the second one and the same thing happens, except he uses it to ward off the hotel staff instead.
- In the Diary of a Wimpy Kid book Dog Days, Greg and Rowley watch a B-Movie called Hello, You're Dead that they found in Rodrick's room, featuring a muddy hand. Rowley has his eyes covered the whole movie. Greg doesn't find the movie all that scary... until the end, when the "muddy hand" crawls straight to the screen, meaning the "hand" is coming for the viewer next.

This leads to them running into a wino, mistaking him for the monster, and running up his front and down his back, and all the way home.

They decide her trauma from watching the movie was punishment enough.
- Johnny Test
- One episode has Johnny and Dukey, after several attempts, getting an M-rated game. They get nightmares after they play it.
- Another episode had Johnny stay up late watching a horror movie marathon despite his dad telling him not to.

- Upon unexpectedly having to work late, The Iron Giant's Annie Hughes forbids her son Hogarth from gorging on snacks, staying up too late, or watching scary movies. So, naturally, he plunks down in front of the TV with a box of Twinkies to catch the midnight Creature Feature as soon as she's gone. And it's his paranoia over being hearing noises after being creeped out by the movie that leads him to leave the house with his flashlight, helmet, and BB gun, and discover the Giant for the first time.
- One episode of the Dexters Laboratory reboot has both Dexter and his dad sneak up after bed time to watch a late night b-movie horror flick.
