I don't know about the rest of you, but TSD episodes are some of my favorite parts of Futurama.  The funniest part being, of course, what they say leading up to you entering the door.  Post more ideas for that here.  Like something that could be said before entering from the announcer's point of view like in the show.  I don't have anything right now, but I'm thinking.

EDIT:

You are entering a place that is odd.
The kind of place where there might be something scary like a house burning in the middle of an ocean.
On that house, something clearly isn't burning.
That house's front door is not burning.
Prepare to enter The Scary Door

This is just off the top of my head, I could probably do better, but it's fun just write down what you think of.

Guineapig Trick tried to start one of these Scary Door threads over in the fanfic section...it didn't fair too well.

What i love about the scary door is the complete randomnes.

"Why should I belive you? You're Hitler!"
  

"Turns out it's man!"
I was so scared that was gonna turn into some crappy celebrity joke... and the F-team give me an incredibly pleasant surprise! 

"You ask a passer by for directions, only to find that he has no face or something." 

The "or something" makes it classic...

OK, 1) It's: You're entering the vicinity of an area adjacent to a location.  The kind of place where there might be a monster or some sort of weird mirror.  These are just examples.  It could also be something much better.  Prepare to enter The Scary Door.
2) You're supposed to post your own, not ones from the show.

I loved the "It turns out it's man!" one, once you remove all the padding you realise just how silly those kind of twists are.

You're entering another dimension. Or perhaps, it's your regular dimension but you have amnesia. And while you're trying to regain your memory, I'm enjoying sex with your wife. Prepare to enter...The Scary Door.

Doesn't quite fit in with the Scary Door, but god that made me laugh 

"The Scary Door" is really funny, but it kind of doesn't seem to fit the show, since there's nothing particularly futuristic about it.  If they put the exact same episodes in, say, The Simpsons, I don't think they'd be particularly out of place.

  Hey, this thread is getting replies!.  That both proves me wrong and makes me happy; as I stated in the other thread, I find this stuff inherently hilarious...


The one from my fanfic:

You are about to enter a realm of which you’ve probably never seen anything much like. Without warning, you’re bound and gagged and put in a shopping cart wearing nothing but a negligee barreling down the steep hill that is the human mind. Perhaps someone important to you dies, or maybe someone dead comes back to life. Maybe both. You’ve reached… The Scary Door.

One I’m making up right now.

You are moving in a direction parallel to nowhere, perpendicular to the unknown, and maybe a little bit Southeast from insanity.    Behind you is something too frightening to imagine.  Let’s say it’s chasing you.  Something eerie darts out in front of you, and you try to turn and run, but then you remember that first thing I mentioned.  Too late… you’re through…  The Scary Door.

I like it!

You want a worthy adversary? I'll give you a worthy adversary!

"While browsing a metaphrorical milkbar, something bizarre happens. You do not know what, or why it happened, you only know what your mother didn't tell you. Then, suddenly, you're falling, falling through a pit filled with doors, each door more locked then the one after it, though some have larger locks then others, and look better made maybe. Finally, one door opens, and you fall through, but triumph turns to terror as your teeth start attacking you. For you have fallen into... The Scary Door."

EDIT: On second thoughts, I'm not that happy with this... I'll change it if inspiration comes...

Wow - ive read them, i can't unread them, i pity the next...scary door intro! 
Well those points aside - here's my pathetic attempt.

Your in bed feeling ambiguous. 
You forget what that means
You go to look it up in the dictionary,
but you're already in your pajamas, so don't.
Now you're dreaming,
You enter a portal that looks like a door,
you open it, it's not.
Your're faced with a something perplexing,
a cartoon viewer, or maybe some kind of monster, an ambiguous one.
You turn back only to find you're facing
The Scary Door.

You're burning down a church in Norway when a cop taps you on the shoulder. When you look down you realize you're not holding gasoline and a torch but rather cottage cheese and a sausage link. Then you look up at the cop and realize he's your mother. You then quickly faint into a black hole of never ending cases of people dying of agony from watching Pepto Bismol commercials. It is at this moment you know you've entered...THE SCARY DOOR!

You think yours sucked Kazzahdrane? I made this up right now and it licks plumber ass cleavage.

Man, all of these are so random.  So random they have to be good!

"You get home from work to find all the beer is missing from the fridge....
Yuu scream quite loudly, enough to wake the neighbours, who are dead, and start to eat your brains....you die quite expectantly and float off into, the scary door...."


"You turn on your computer and discover all your bookmarked sites have been erased by an unkown assailant, who happens to be standing right behind you....he grabs your face and starts pulling on it....you try to move but seem to be stuck to the chair, not really actually you're just paralysed from the waist down....you try to scream but no sound comes from your mouth....it appears your mouth has been taken from you....you go to thescarydoor.com and curse your dial up connection as you wait for it to load, and take you away....

Yeah, once I started I couldn't stop....take THAT....!

You're entering a parallel universe. Or maybe a perpendicular dimension. Perhaps a little from column A and a little from column B. Let’s call this new column, "Column C." Oh, and now you're gay. Prepare to flamboyantly enter...The Scary Door.

You are sweaty and going for a nice shower.  You turn on the faucet, but all that comes out is sand.  You try to turn if off, but the knob won't budge.  The bathroom fills up with sand and you would've drowned, had an arm not seamlessly come up through the floor and pulled you down. Down to the downstairs of your house.  You now see a person, the person that saved you.  He duplicates himself so that he is all around you and all of them turn into connecting doors.  You are surrounded and all the doors lead to the same place.  Pick a Scary Door.

"You are walking through a black void. Various objects keep appearing around you and then disappearing - these are probably meant to be symbolic of something or other, but you're not sure what. You walk through a door in front of you only to be confronted by the words... The Scary Door"

You wake up in your bed in an alternate dimension, or maybe an adjacent dimension like the bathroom window. They could be the opposite ends of the same spectrum, or maybe same ends of the opposite spectrums. All you know is that doors are made of ham and bratwurst in this universe, and they're all called...
The Scary Door
