Here's 4 of my favorite Treehouse of Terror skits..

#1:

Master Sword Dinky, and Derpy are employed as caretakers at a mansion. However the caretaker cuts the cable television wire and confiscates the beer, thinking this will ensure hard work from the family. While there the groundskeeper discovers that Dinky has power to read thoughts and says that if his Sword goes more insane than usual, that she should should use this to summon him. Dinky is confused about this, but the groundskeeper doesn't add anything more.

Sword goes to turn on the TV but finds static.

Sword: (calmly) Hmm, cables out.. Maybe I'll have a beer, annnnd there's no beer in here, haha, how lovely.

Derpy: Sword, wow, your taking this very we-

Sword: I'll kill you! I'LL KILL ALL OF YO-

Derpy: Sword!

Sword: Kidding, kidding, maybe I'll check out that axe cellection.. See you later (leaves).

Dinky: Mom, your boyfriend gonna kill us?

Derpy: Guess we're have to wait see.

Sword goes down to the bar, where a ghost drops all settlty and tells Sword he must kill the girls.

Derpy goes to check on Sword to see he wrote "no TV no beer make Master Sword crazy." And Sword himself bursts into the room, Derpy screams.

Sword: (eerily calm) So, what do you think, baby? All I need is a title. I was thinking of something along the lines of "No TV and no beer make Sword..." something something.

Derpy:: (nervous) ..."Go Crazy"?

Sword:: (hysterically) DON'T MIND IF I DO! (goes on a wacky rant)

(Derpy screams and smashes open a case labeled "Break glass in case of boyfriend's insanity" and grabs the baseball bat within).

Derpy: Stay away from me!

Sword: (chases Derpy up some stairs) Give me the bat, Derpy. Gimme the bat. Gimmethebat! Come on! Gimmethebat! Gimme the bat! Gimmi the batbat whoo! Ha ha ha! Scaredy cat! (makes scary face) Bleaahhh... (sees himself in a mirror) AAAAAHH! (falls down the stairs, knocking himself out; Marge leaves his unconscious body locked in a pantry)

Derpy: You stay here til your no longer insane. (locks him in).

Sword is seen eating a bunch of stuff in the pantry is back to himself eating happily until a bunch of ghouls drag him back out of the pantry.

Derpy and Dinky are enjoying dinner.

(Sword chops through a door with an axe)

Sword: Heeeere's Johnny! (the camera pulls back to reveal an empty room) Dammit!

(Sword chops through a second door)

Sword: Daaaaavid Letterman! (wrong room again).

Abe: Hi David, I'm Grampa!

(Sword chops through a third door)

Sword: (holding a ticking stopwatch) I'm Mike Wallace, I'm Morley Safer, and I'm Ed Bradley. All this and Andy Rooney tonight on 60 Minutes! (evil smile)

The girld: Aaaaah! (they get up and start running, Dinky uses his powers to summon the Groundskeepers, who immediately runs to the family's rescue, abandoning his portable television in the snow in the process. However Sword easily kills him by striking him in the back with the axe.

Derpy: Oh my, I hope that carpet is scotch-guarded.

Sword pursues the girls outside but as he is about to kill them, Dinky discovers the abandoned television. And shows it.

Dinky: Sword look!

Sword: Television! Teacher! Mother! Secret lover... Urge to kill fading...fading...fading... (family approaches)RISING!...fading...fading...gone.

(The girls sigh in relief).

Sword: Come family.

They end up frozen there.

TV: And now the Tony awards.

Derpy (frozen): Sword, change it!

Sword: Can't, frozen!

(they all scream as the Tony awards begin).

Sword: Urge to kill.. Rising.

#2:

Saten Twist's hammock collapses while he is taking a nap. He purchases a new one from a passing vendor, who warns him that it carries a curse. Disregarding this, Saten lies down and discovers that the new hammock can produce clones of anyone who rests on it. He inspects the first clone and notices that it does not have a belly button.

He makes clones to do all of his chores, which include helping Trixie choose an outfit, playing with Dinky, and dong housechores.

The clones are far less intelligent that him. Glaze asks for help chainsawing some trees, so Saten sends a clone. Who later returns, showing off Glaze's decapitated head and happily showing it off, scaring Saten.

Taking it as a sign this is getting out of hand, Saten abondons the clones in acornfield. Asking if any remember the way home. A few raise there hands, and Saten shoots them with a gun he brought. Leaving the rest, as well as the magic hammock.

However, the clones use the abandoned hammock to make an army of Saten Twist clones.

The clones attacks Ponyville and destroys all of its buildings, except for Maggie's bar, which reports record business.

The pony army officials gather in the Mayor's War Room, and determine that the clones will eat up all of Equestria within a few days. Derpy thinks of a solution to solve the problem, after getting the idea from Saten himself, who became upset when he found an empty doughnut box.

Helicopters hook gigantic doughnuts on cables and lure the clones to their deaths.

In the end, Trixie is shocked to find that the Saten Twist she went home with is a clone, and the real Saten Twist appearently was the first to jump off the cliff.

Trixe freaks, until the clone gives her a backrub.

Trixie: Oh well.

#3:

Derpy sees every muffin store closed. And states that he would sell his soul for a muffin. The devil himself appears and offers her a contract to seal the deal.

Derpy: Hey, wait. If I don't finish this last bite, you don't get my soul, right?

The Devil: Well, technically no...

Derpy (singsong) I'm smarter than the de-vil! I'm smarter than the de-vil!

The Devil: (morphs from normal to Chernabog) YOU ARE NOT SMARTER THAN ME! I'LL SEE YOU IN HELL YET, DERPY HOOVES! (shrinks and disappears)

Derpy: Pfft, yeah right.

Unfortunately, while half-asleep and looking for a midnight snack, Derpy eats the final piece of the "forbidden donut", and Lucifer instantly reappears to take possession of her soul. But Glaze was there and pleads with the devil, finally getting Lucifee to agree to hold a trial the next day. Until then, Derpy is sent to spend the rest of the day being punished in Hell.

Her first punishment is to be strapped down and force-fed "all the doughnuts in the world!".

(a machine begins force-feeding Derpy muffins two at a time; the scene fades to several hours later: the wall of donuts are gone, the machine is still force-feeding a bloated but smiling Derpy.. and she's still going)

Derpy: More!

Demon: (frustrated) I don't understand it! James Coco went mad in fifteen minutes.

#4:

Glaze, Trixie, and Derpy are kidnapped by aliens. The aliens explain that they are taking the girls to their home planet on Rigel IV, "a world of infinite delights," for a 'feast'.

En route they present the ladies with enormous amounts of food and watch eagerly as they gorge themselves, then check their weights.

Suspicious of the alien's intentions, Trixie sneaks into the kitchen and finds a book titled How To Cook Ponys. She takes the book and confront the aliens, who explain to her that part of the title was obscured by space dust, which they then blow away to reveal the title How To Cook For Ponys. Glaze, skeptical at this, blows off more space dust, revealing the title to be How To Cook Forty Ponyss. The aliens blow off the last of the space dust, finally revealing the real title How To Cook For Forty Ponys.

The aliens reveal they simply wanted to serve them some food, that was all. And that the mistrust even made the cook cry.

They return them to Earth, explaining that they simply wanted to take them to a paradise on the aliens' home planet. But now they ruined their chance.

I was also gonna add "Dial Z for Zombie", but decided against it.. As well as the Drucala one.. The one with the school cannibals.. And the Freddy Krueger one..

I might still do the one where the house wants Marge.. Plus BalorBabe requested one..
