PINKIE PIE: "Yeah... probably not my finest hour here. Making copies of yourself to hang out with all your friends at the same time - let's just say it's not nearly as fun as you might think!"

TWILIGHT: "Yes! Finally, I'm a Princess!"
SPIKE: "...Where's the punchline, Twilight? We're all waiting."
TWILIGHT: "Punchline? I'm a Princess now, Spike. I can't go around tossing out quips and jokey asides."
SPIKE: "But... just last episode you were all snarky and remarking for characters of the day to not come back! What happened?!?"

PINKIE PIE: "...yeah, I don't really like looking back at this phase of mine either. Let me tell you, I was really wacko! If I saw any of my friends acting that way, I'd have them committed! Maybe let them out on weekends for a bit of fresh air."
[Rainbow pushes away with her foot a filled-out asylum form]

REMANE 5: "Surprise!"
RARITY: "Wha...! But, I... what are you all doing here? You're cutting into valuable screentime for me to chew the scenery! I was saving all that for the episode's last third!"

One of these things is not like the others,
One of these things just doesn't belong,
Can you tell which thing is not like the others
By the time I finish my song?

PEACHBOTTOM: "Whoo-wee! That welcome you threw for me really was something! Why, if this were a hotel, I'd give it five stars!"
TWILIGHT: "That's, um, great. But could you, you know... not come back for any future episodes? Thanks."
APPLEJACK: Twilight! Why in Equestria would you say such a thing?

DIAMOND DOG: "My... precious..."
RARITY: "Oh, please, not-darling, that reference is so overdone."

SPIKE: "Oh yeah, I remember this! The time when I went from just another sidekick to a hero in my own right. And it showed all those naysayers you weren't a token princess either, Cadence!"
CADENCE: "Wait - who was saying I was just a token Princess?"
SPIKE: "Uh... the Shadowbolts?"

KING SOMBRA: "Crystals..."
[clears throat] "Wow, small wonder I became something of a joke in the fandom, if that was all I got to say for nearly six seasons."

SPIKE: "That Angel Bunny. Up to no good as usual! And here I thought Discord caused chaos."
DISCORD: "You rang? Oh, all these pets sow plenty of chaos, you know. Why, I should stick around to see it -"
SPIKE: No, Discord. We're not doing that."

TWILIGHT: "Winter Wrap Up, Winter Wrap Up, our song is so iconic that even the show itself referenced it twice in Season 4!"

Pinkie: Wait… so you're telling me there were other adventures we got up to in between Twilight getting her castle and Starlight joining our harem posse?!? And our audience never got to see them?!?
Stop the presses! This calls for an emergency cupcake! And perhaps an emergency party. Okay, definitely an emergency party.
