Nightmare Fuel: Tales from the Crypt
This show liked the twist endings; therefore, be aware of heavy spoilers below.
For starters there's the Crypt Keeper himself, in all his rotting corpse glory.
The twist endings. The plot for "Ear Today Gone Tommorow" is about a man 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 jaw cracks and he develops an owl's beak. There's also the show finale "The Third Pig", a rather twisted take on the classic fairy tale Three Little Pigs.
In syndication, maybe, but the uncut HBO version shows it in all its Nausea Fueled glory. Definitely more gruesome onscreen.
Tthe 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.
Joe Pesci being cut in half with a chainsaw so a pair of psychotic twin sisters can each have him as "theirs." With close-up of his mutilated insides. Lovely...
There's one where 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-Kadaver? 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 one where Lee Arenberg (Pintel from Pirates of the Caribbean) played a nightclub owner that killed his partner - overall, it was a surrealist take on The Telltale Heart, with the voice of the victim nagging on him about his death, etc. What pushes this into nightmare territory, though, is at the very end, the guy 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 tells him that they're not looking at him because they hear the voice too... it's because he's got Q-tips shoved in his ears so far that he ruptured his eardrums.
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 on live TV.
