"You will never defeat me, Twilight Sparkle!" Nightmare Moon sneered at Twilight.
"I will! For Princess Celestia!" Twilight shot back.
Nightmare Moon laughed. "You ridiculous foal. Once you know the truth that Celestia hid from you, you won't even want to fight me!"
Twilight blinked. "Princess Celestia never hid the truth from me!"
"Didn't she? What did she tell you about what happened to your mother?"
"Wait, what does my mother have anything to do with this?"
"Twilight, I AM YOUR MOTHER!"
Twilight stared at Nightmare Moon in disbelief. "Oh, come on, now, am I expected to buy that?"
"Search your heart!" Nightmare Moon said. "You know this to be true!"
"I know this to be one of the oldest cliches in the book!" Twilight said.
"Actually," Pinkie said, "it just dates back to the 80's when The Empire Strikes Back came out!"
"Ok, but still, that's pretty old," Twilight said.
"What, and eternal night is fresh material?" Nightmare Moon said. "I have to work with what I've got! Now join me, in the dark side of the... darkness!"
"You girls getting all this?" Twilight asked her friends.
"Yeah," Rainbow Dash said. "Totally lamesauce. 'Dark side of the darkness?' Isn't it supposed to be the dark side of the moon?"
"Well, um, there's no dark side of the moon, really," Fluttershy said. "As a matter of fact, it's all dark."
"Why, Fluttershy!" Rarity said. "I would never have guessed you to be a Pink Floyd fan!"
"How in the hay is Twilight supposed to believe you're her mom when you've been on the moon a thousand years?" Applejack asked. "Ah know you like to throw the word 'foal' around a lot, but seriously, Your Highness, we weren't born yesterday. And ain't none of us born a thousand years ago, neither."
"I don't know how it happened!" Nightmare Moon said. "Just go with it!"
"Um, no," Twilight said. "I have a better idea. How about we use the Elements of Harmony and defeat you?"
"NOOOOOOOO!"
"Sheesh, you'd think we just told her that the special somepony she sacrificed herself to the dark side to save died because of injuries she caused, or something," Pinkie said.

Oh, wow. Is that really a thing in fanfiction? That's almost sad.
The chapter was funny though.

Not all of the parodies are of fanfiction; some are general pop culture parodies. I don't actually see a whole lot of "Twilight I am your mother" (or the equivalent thereof), although Discord has been the father, the son, the brother, the uncle, and the lover of Celestia and/or Luna in about a zillion different fics (not usually all at the same time, thankfully).

Good point and I know what you mean. Everyone wants to be related to Discord! When they aren't beating him up to show how awesome they are.
With Discord, everything is plausible and always should be, as long as it's hilarious.
Edit: I'm a moron. You only mentioned Celestia and Luna, but I have seen plenty of relatives for Discord.

"Pinkie, I am your father. Search your heart, you know this to be true."
"Okie dokie lokie! Does that mean we get to have a family reunion party?"

"Only the finest of parties based around reuniting with loved ones! Incidentally, I'll make it so big, beautiful, and boisterous that we'll summon your twin brother to help plan it! He does that, you know."
"..." *smacks Discord so hard that his head spins around 360 degrees*
"Ohhhh! Goodness gracious me! So violent. You... you wound me deeply. I meant Pokey Pierce!"
"...?" *remembers who she's speaking to* "No you didn't."
"Would you believe in miracles if I said it was Bulk Biceps?"
"And to think, for one shining moment, I respected you."
"Your mother was Surprise! I swear! Surrrpriiiiise!"
"Uh, wow. You're really committed to this bit, huh?"
*stops sobbing* "You need to be more gullible. I had this giant gala level thing planned for maximum mind-mucking and you had to go and ruin it before I even got it off the ground! Literally. Off the ground."
"Well, the Gummy-Tears didn't help you in believability-ness, but we could always have a party anyway. There's an occasion for every celebration! This one is gonna be called 'Don't Mess with the Pinkster!' Because there are some things you just don't joke about."
Sorry my CheesePie is showing in full force. I'm a go bed sleep now 'kay bye
