This show liked the twist endings; therefore, be aware of heavy spoilers below.
For starters there's the Crypt Keeper himself, who's pretty damn ugly, even if he is pretty goofy in terms of personality. The show itself, as one would expect of an uncensored horror 'short story' show, can dabble between this and Narm, depending on the episode.
The opening sequence can be pretty nightmarish if it's your first time watching it. You get to tour a pretty creepy-looking haunted house before eventually coming upon a coffin, which suddenly opens to reveal the Crypt Keeper, laughing maniacally.
The twist endings. The plot for "Ear Today Gone Tommorow" is about a thief who gets an operation that gives him the auditory system of an owl. Unfortunately, it also gives him other owl-like traits, and at the end his jawcracks open and he develops an owl's beak.
In syndication, maybe, but the uncut HBO version shows it up close, along with a shot of the guy pulling out a loop of intestine and slicing it open to extract the pearl. Definitely more gruesome onscreen.
The episode where Ed Begley, Jr. plays this asshole cemetery plot salesman who gets kidnapped by a psychotic redneck family and gets raped by the redneck family's ugly daughter. Oh, and did I mention that the mother, father, and daughter in this redneck family are all played by Tim "Dr. Frankenfurter" Curry? Noted in that it is kind of similar to that movie Nothing but Trouble (which interestingly featured a music score by Michael Kamen, who also scored the music for this episode).
Joe Pesci being cut in half with a chainsaw so a pair of psychotic twin sisters can each have him as "theirs." Starting at the crotch. With a close-up of his mutilated insides. Lovely...
In "Beauty Rest", a wannabe model murders several rivals so that she can win a rigged beauty contest and become the new "face" of a mysterious company. She does win the pageant, but then it's time for her to appear in the "grand finale." Next thing we see is the pageant host singing a cheery song about how beauty is great, but "it's what inside that counts" as the winner is unveiled: she's been nailed to a board, completely eviscerated, and the audience oohs and aahs over her as she is now the reigning "Miss Autopsy 1992."
How about Abra Cadaver? A good deal of the episode is told from the POV of a man trapped in his own body thanks to his vengeful brother, who is on the verge of getting cut apart at a medical school. Sure, it turns out to be a prank, but the final shot is of him about to get cut apart...while still feeling everything.
One of the worst was "For Cryin' Out Loud", where Lee Arenberg (Pintel from Pirates of the Caribbean) played a nightclub owner whose conscience finally gets through to him after decades of trying - just in time to advise him against embezzling charity money in an abstract of The Telltale Heart, but a bit more literally once he murders his blackmailing banker. What pushes this into nightmare territory, though, is the final sequence. Marty has used Q-tips throughout the episode to try and clear the voice out of his head, and is shown at one point mashing them against his ears in a funny way. But then he's shown wandering through the club, unable to hear anything but the persistent voice, and seeing people stare at him oddly. After blurting a confession to murder, the voice in his head has this to say, prompting Marty to pull over half of a bloody Q-tip out of his left ear.
And for bonus points, said voice was Sam Kinison, so the fact that he'd been on death-row for two years hearing only Kinison's voice adds another layer to the whole thing. No wonder he was so eager to die!
In one episode, a woman marries the boss of a gang of lumberjacks. She is so bored that she begins an affair with one of the other lumberjacks, but cries rape when her husband catches them, resulting in the husband attacking the guy with an axe and blinding him. The other workers' response is to kidnap the woman and her husband and place them inside hollow logs for the blind lumberjack to chop up; he realizes what is happening fairly early on, but joyfully goes through with it anyway. There's a lovely gory shot of the bodies chopped into four parts.
"Television Terror" non-stop. The setting is a Haunted House, where an old woman murdered her elderly borders for their social security checks years earlier. TV host Horton Rivers enters with his cameraman to investigate the hauntings, despite a psychic consultant's warnings. Horton begins seeing flashes of the gruesome murders, and then the doors open and close on their own. When the psychic finally warns him to get out of there now, the cameraman is revealed to have been hanged and the ghostly victims come out in force. Horton fares worse, getting on the wrong end of a chainsaw wielded by the old woman's ghost before going out the window and hungon live TV.
The scary part about this episode is that while most of the episodes range from pure camp this one stands out enough that it could have made a stand alone horror film.
"You Murderer" Could be considered this for those who fear what could happen to them after they die. They end up in an And I Must Scream situation.
The zombies in "None But The Lonely Heart". The two most recently deceased (whose deaths we saw in the episode) are rotting and slimy. The third is little more than a dried-up, mummylike husk. The fourth is a worm-ridden skeleton in a rotting wedding dress. The episode ends with all of them cornering the protagonist in a mausoleum and chowing down on him with a nauseating crunch.
There's the show finale "The Third Pig", a rather twisted take on the classic fairy tale Three Little Pigs. It's also the only episode of the show to be animated as opposed to live-action. That doesn't make it any less frightening.
