MLP: FiMComedyRandomHumanTwilightSelf Insert
Staying in Twilight's Castle, you make the terrible error of flippantly calling her 'Hitler'. She demands a history lesson (for archiving purposes, of course) and you give her one that ends up being far more frustrating than you had anticipated.

It's been three months since Princess Celestia appeared in your bed. Three months since she took that bed, along with your sheets and your pillows. Three months since she nearly drove your girlfriend away from you. But peace was made, and everything had been going relatively smoothly. Life was even beginning to look up.
Until today.
A spin-off of Ocalhoun's Princess Celestia is in your bed.

Many might claim that opening portals into dimensions that don't even technically exist is a waste of good time and energy. Princess Celestia, however, does not.
On a day seemingly designed to produce boredom, Princess Celestia decides the most effective method of alleviating such a pretentious feeling is to involve herself in a rather humorous conflict by successfully acquiring the "enemy intelligence".
She correctly assumes that the beings from whom she stole it from are not pleased. However, she never could have foreseen the incredible lengths they undergo to retain their dignity.
A pony walks into a bar. A very royal pony. She proceeds to drink far more than she should. She also cheats at ping pong.
Written as a next step for This story, with ROB's encouragement and help.

Celestia and Luna announce their retirement and their plans to turn the throne and power over Equestria to the mane 6. Unfortunately, this is the last straw for Twilight, and she goes off on a rant about why this isn't a good idea.

Discord has only been improving, and Twilight wants to reward him with a little more responsibility. As a thank you, Discord rewards her with a shiny new vending machine for the Crystal Tree.
The problem? That vending machine dispenses bees.
Twilight now has a castle full of bees that will attack of she thinks the wrong kind of thoughts... That being said, if she thinks the right ones...

Word around Ponyville is that Queen Chrysalis is planning something.
Something big.
Something terrible.
Something beyond imagination.
If only Queen Chrysalis had any idea what that something was.

You stumbled apon facing the toughest challenge since coming to Equestria; fighting off three overpowered villains with a bell to take all the magic from the ponies. It is up to you to help stop them from getting more powerful by using yourself as bait. When Chrysalis encounters you though, a clever idea struck your vision.
To ask her out!

What did you expect when a two hundred and fifty pound horse hits you at the speed of sound?

Rainbow Dash is very angry with you over something you have said.
So, you must face the so called 'terrible consequences'...
Once again, a big thanks to Ravvij for helping me with editing to improve the story overall.

Anon has noticed something strange. Rainbow Dash doesn't live in Ponyville or Cloudsdale, and her house never stays in one place. Because of this, it seems that she basically lives in a trailer home, making her... trailer trash! The implications of this realization are anything but pretty.
Please be aware, this is for silliness and for fun, not because I hate Rainbow Dash. Everyone knows I hate Spike, come on.
Thanks to Enigmatic Otaku for the idea.

Twilight invites Ryan over to the Library for a standard 'read and chill' session that the two have with some regularity. This time, Twilight, has other plans; plans that she hopes will have a much more raunchy end to them.
It goes about as well as one would expect.
A short, simplistic oneshot.

Rainbow Dash just wants somepony to read her manuscript now, not 'later'. (Which we all know means never.)

I wasn't supposed to be where I was now. Or at least that's what the light in my dream said to me. I was supposed to be a "creator of worlds" it said. I was to create fate or something like that, and manage the lives of millions. But what can I do in a world that doesn't need saving? What can I build with the tool gun to change my fate? But more importantly, why was I chosen to wield such power over said gun?

Twilight Sparkle is often cited as being a prodigy. What if that fact is truer then previously believed? In this alternate scenario Twilight develops alicornhood much sooner thanks to the magic surge during her entrance exam. What follows is chaos as the lavender pony maneuvers herself in this crazy new world. Meanwhile, those in the old aristocracy either try to remove the filly or attempt at taking full advantage of her. These are the adventures of an innocent filly who has to contend with the adult world. Silliness is all but certain.

Inspiration for this story goes out to Georg. If you want to read another filly alicorn story go here: http://www.fimfiction.net/story/143216/letters-from-a-little-princess-monster
Some try to write fics about Twilight as a child alicorn, some about her early years as a student, fewer still try to write about both. Hopefully it works.
Good news, it turns out someone made a tvtropes page.
