Equestria Girls short:
Chaos in Math Class: Why is Mr. Cranky Doodle so cranky, anyway? Right now, he can name three reasons: Apple Bloom, Sweetie Belle, and Scootaloo.
Cranky: “Sweetie Belle, you were supposed to get a parent to sign this…”
Sweetie Belle: “I got Rarity to sign it. If she’s qualified to have her own business, she can sign one lousy math test.”
Cranky: “I don’t care if she won the Nobel Prize! I asked for parents, not older sisters!”
Sweetie Belle: “You let Apple Bloom’s big sister sign.”
Cranky: “That’s different! Apple Bloom doesn’t HAVE any parents!”
Apple Bloom: “I’m right here, ya know!”
Cranky:
(Fumbles for words, then lets out an exasperated sigh.) “Fine. I’ll let it go this once. But pull this stunt again and you’re looking at detention, missy. Okay, who’s next? Scootaloo…”
(Picks up test, eye begins twitching.)
Scootaloo: “What’s wrong? I had my big sister sign it, just like they did.”
Cranky: “RAINBOW DASH IS NOT YOUR SISTER!”
@Jarkes
Thanks! I actually kinda have a follow-up for it…
Lightning Strikes Twice: To help Lightning Dust develop into a team player, Rainbow Dash arranges training with Vapor Trail and Sky Stinger, whose teamwork is better than any other pair of ponies she knows. Things seem to be going great until Dash makes the mistake of mentioning it in front of Thunderlane, who’s still bitter towards Dust for repeatedly shoving him aside at the Academy. At their next practice, Dash warns Dust, Sky, and Vapor that Thunderlane might try to give them trouble. He shows up right on cue, bringing Spitfire with him.
Spitfire wants Dust gone, which isn’t helped when Dust shows that, while she’s grown enough to admit she’d done wrong, she’s still a little bitter towards Spitfire for how she managed the incident (“Everything I did, you encouraged. Right up until you swept me under the rug. Did I really look like a lost cause, or were you just too ashamed to deal with me?”), but Rainbow Dash intervenes and reminds Spitfire that she’d once said that that being meant not just pushing yourself, but pushing yourself in the right direction. And shouldn’t mean that when somepony else is trying to push herself in the right direction, you should help her push through, instead of pushing her away? Reluctantly, Spitfire agrees, and prepares to re-evaluate Lightning Dust.
As in within the next five or ten minutes, which means Lightning Dust’s second chance is riding on four tired pegasi, a routine they’ve barely had a chance to practice, and one of the most difficult aerial maneuvers ever attempted: the Orbital, in which one pegasus repeatedly circles another as they fly. While Sky and Vapor perform the Orbital flawlessly, Dash and Dust can only keep it going for ten seconds… Which is still seven seconds longer than Spitfire expected them to, and enough to convince her that Lightning Dust could be something special (so long as she doesn’t screw up like last time). As such, she’ll be considered on probation during her time at the academy, but she’s also guaranteed a spot in the next group of cadets.
Dust and her trainers briefly celebrate their success before hitting the showers while Spitfire heads back to the barracks, accompanied by a confused and conflicted Thunderlane.
…That was way longer than I meant it to be.
