Punky goes on a camping trip with her ethnically inclusive friends, and they promptly get lost in the wilderness. The group takes refuge in a cave, and Punky tries to pass the time (until, presumably, they starve to death) by telling a ghost story about four kids that get lost in the woods and find refuge inside of a cave. It's either a bad attempt by Punky to be meta, or they couldn't afford a second set. Either way, if kids looked down for just a second, or took a bathroom break at the wrong moment, it would have been easy to miss the fact that what happens for the remainder of the episode wasn't actually happening to Punky and friends, which is important for terrifying reasons that will soon become apparent.

Punky's story is quickly interrupted by a group of Native Americans, who are apparently synonymous with cavemen, and they have a much better story they want to tell about unspeakable horror.

The kids hear a story of an evil spirit that, as it happens, lives in the cave and that, as it happens, can be killed only by Punky Brewster. The kids, with little concept of mortality and poor decision-making skills, head deeper into the cave. Along the way they encounter the type of horrors you would expect from a sitcom, like kindly but unnerving lost souls and some spiders.

But gradually the story stops being fun and starts to resemble the Blair Witch Project. Punky's friends vanish, and she can hear their screams for help bouncing off the walls. When Punky finally builds up enough courage to demand that the evil spirit give her friends back, it screws with her by revealing the decapitated head of her friend Alan, stuffed into the side of the cave, still crying.

Her friend Cherry's head also appears from behind a wall, floating in the air with eyes glowing red. Finally the corpse of Margaux falls from the roof, decomposed to just a skeleton with a rotting face screaming at Punky.

The only friends of a scared little girl are now just faces of soulless evil surrounding her, calling out her name. Here is a video of this horrible 45-second sequence of events:

After Punky finds a place to sit and mourn her dead friends, she also has a vision of her foster father giving up his search for her and deciding that maybe life would be better without Punky. Notice we said "foster father." Punky is an adopted kid, likely with abandonment issues, who witnesses her best friends turning into the undead and the only man she's ever called "Dad" giving up on her. The only friend she still has is her dog ... right up until he turns into a skeleton.

At this point, the evil demon finally shows up with knives for hands and threatens to turn her into a mouse and feed her to snakes.

After defeating the spirit with love, somehow, the ending reveals that this was all Punky's ghost story and that none of it ever happened. It would have been hard to keep the show going after murdering three children and turning Punky Brewster into a spirit killer. Still, it was a two-part episode, which means that kids everywhere had to wait a week to find out that their favorite adorable sitcom had not in fact undergone the grittiest reboot ever.

The only children in the show were really just secondary characters and rarely part of the plot, partially because it was geared toward adults, with topical issues like racism and homosexuality, and partially because Edith was really the child on the show. Archie's wife is so wide-eyed and optimistic in every episode that her ignorance is completely forgivable. She has the innocence of an infant, so it's especially difficult to watch the two-part episode entitled "Edith's 50th Birthday," where she is very nearly raped in her own house.

It all starts when a police officer drops by while everyone else is planning a surprise party for Edith next door. He tells Edith that he's investigating sexual assaults in the neighborhood. It's not until he starts to describe the rapist he's looking for that Edith realizes he's describing himself.

Edith tries to offer him money to leave, but he pins her to the couch for an intensely awkward five minutes and starts undressing while kissing her neck. Keep in mind that her family is also just next door, trying to make this the happiest day of the year for her.

Edith, in her unrelenting innocence, tries to cite her advanced aged and marital status as reasons that she would be an unacceptable rape victim. Her captor simply replies that he enjoys older women and that he is married himself. All across America, millions of families glanced awkwardly at one another and shared a silent look of "Are we actually seeing this?"

The hardest part to watch, however, is the moment Archie comes home briefly to grab a punchbowl as the assailant hides in the closet. You can see the terror on Edith's face as she wants to tell the man she loves to save her, and he still walks out the door, completely oblivious to the circumstances.

Edith escapes only when a cake starts burning in her oven and the rapist allows her to take it out. With some quick thinking, she turns her birthday into a weapon and slams the cake in his face before running out of the house.

When the police finally arrive and try to get Edith to identify the clothes of her attacker, all the lightheartedness that was left in the episode stops immediately. Edith goes into a blind panic so unnerving and uncharacteristic of any sitcom ever that the studio audience doesn't know how to respond and so just applauds, hoping that somehow it will fix everything.

Watching the episode will not only make you feel dirty, but also ruin every surprise birthday party you ever attend.

At first, Mr. Horton just seems like a nice old man, and that's exactly what's so horrifying about this episode -- it's the slow reveal that a character is actually a pedophile trying to seduce Arnold with ice cream and comic books. It's not until he asks Arnold never to tell Mr. Drummond about the time they spend together that something seems slightly off.

Arnold likes Mr. Horton so much that he starts bringing his friend Dudley along, and it isn't long before Mr. Horton is feeding them both wine and giving them pornography.

He even tells the kids about all the cool games that they can play with their clothes off and shows them naked pictures of himself, which the studio audience apparently finds hilarious.

The day culminates in Mr. Horton getting Dudley to take his shirt off for some photos, and Arnold returns home with the smell of wine still on his breath. He is caught by Dana Plato and Todd Bridges, who make him swear to never drink again.

Dudley and Arnold continue to visit Mr. Horton until the whole thing gets a little too creepy for Arnold. He decides to do the moral thing and leave the bike shop ... incidentally also leaving his best friend with a pedophile. Solid work, Arnold.

Eventually Arnold tells Mr. Drummond about what's been happening, and the police arrive at the bike shop just in time to find a drugged up, half-naked Dudley sprawled out and Mr. Horton doing a few warm-up stretches in preparation for some vigorous child abuse. Mr. Horton is arrested and Arnold and Dudley learn an important lesson about trusting strangers. Or sitcoms.

Too Close for Comfort was a show about a cartoonist named Henry Rush and his wife, Muriel. They had two adult daughters who lived with them, along with a moronic tenant named Monroe. This setting, which would seem to encourage at least a small amount of sexual tension, instead insisted on concentrating on a bunch of wacky personalities just trying to get along.

But the dynamic takes a dark turn in the episode "For Every Man, There's Two Women." Monroe does not come home one night from his job as a mall security guard. He finally returns in the morning with his uniform partially torn off, looking shell-shocked.

While it takes him awhile to calm down and explain what happened, he reveals that he had been kidnapped from a parking lot and forced into a van by two women. He was then taken to an apartment and raped throughout the night. He tells it all to his quasi-family, clearly shaken by the experience, and the studio audience laughs along.

Henry eventually calls the police department, which dispatches maybe the worst SVU detectives in the history of law enforcement. They take some basic information and then tell Monroe it's not worth pressing charges because it would be too embarrassing.

To give the proper context, the drama 21 Jump Street came out with an episode called "Hell Week " around the same time as this episode aired, and it dealt delicately with the atrocity of sexual abuse. Too Close for Comfort builds so many jokes around rape as a concept that we almost suspect the audience is filled exclusively with prison inmates.

Henry and Monroe finally find and confront the women who raped him, and both of them are easily over 200 pounds and terrifying. It quickly becomes evident that this was a legitimate crime. Henry barely escapes before almost suffering the same fate as Monroe, and the women are arrested. Then, in one of the most unintentionally sad moments in sitcom history, Monroe thanks Henry, and tells him that it's nice to know that if this ever happens again, he will be there to help guide and protect him. Henry immediately tells him that next time this happens (read: Monroe gets raped), he's completely on his own.

Yes, Diff'rent Strokes makes the list twice, the second time in a transparent attempt to top the whole bike shop pedophile affair. And this time, the plot is so egregiously dark and narrow in focus that it's not entirely clear what the moral of the episode is, other than that sometimes life is an unthinkable nightmare.

"Sam's Missing" starts when Arnold gets a new stepbrother, Sam, and immediately begins bossing him around by making him run errands for him. On one of these errands, Sam meets a man whose family is in an emotional tailspin due to the fact that their son was recently killed in some kind of accident. He convinces Sam that he needs help finding his lost dog, which is actually just a ruse to take Sam home as a replacement for his dead son.

Worst of all, when Sam objects about the two-hour drive, the kidnapper tells him Sam's family will be harmed if he doesn't cooperate. The man introduces Sam to the rest of the family and, just like in Texas Chainsaw Massacre, it turns out they're all crazy. The father makes up a story about finding him in a box, and the rest of the family agrees that sounds like reason enough to keep him.

To prove the show isn't just playing around with the idea of kidnapping to heal emotional scars, Sam isn't rescued right away. He stays with the family for around a week while Mr. Drummond goes on television and offers a $50,000 reward for Sam's return, along with a tearful plea to the kidnappers to do the right thing.

Over the next few days, Sam tries to keep from having a mental breakdown with his new family. When he has trouble showing affection or any emotion other than fear (which is always), he gets more threats of what will happen to his real family if he doesn't cooperate.

Meanwhile, in a staggeringly cruel turn, Sam's real family gets a call after five days from someone claiming to have the boy, but it just turns out to be a crazy ex-con trying to claim the ransom money. Keep in mind that from the perspective of a child watching this episode, it's terrifying enough to introduce a family so sad about the death of their child that they would steal another one. Then they have to introduce a despicable new character that would lie about kidnapping kids just to get some money? Damn, this show liked to pile it on.

Eventually, Mr. Drummond figures out where the boy is and comes to the rescue. The police burst in and rescue Sam while the kidnapper's family mentally unravels, only proving that even people who have never done anything wrong still get mentally tortured for no reason.

Sam is returned home, and the entire family goes back to being happy and normal ... or as normal as it can be for a child who just went through a week-long abduction where he was forced to call another family "mom" and "dad." Also, when the mother and father of that family are sitting in jail cells, we don't get any indication of what will happen to their other, surviving son.

In the Diff'rent Strokes universe, all we know is that it probably ended in screams.
