Turnabout Storm/Shout-Out

Being a crossover between 2 series that are filled with Shout Outs, it's only natural they would show up.

"Phoenix: I'm not whining; I'm complaining!"
 * Albeit unintentionally, Phoenix says he read the book Twilight gave him on Equestria in 10 seconds flat.
 * He later unknowingly borrows another memetic phrase, this time from Rarity:

"Phoenix: (I should really tell her I just stole that one from a video game.)"
 * And he also borrowed a proverb from Mei Ling, but this time knowing where he got it from.

"Franziska: You have no chance. Zero. Zilch. Nada. I'm not losing this case! Trixie: The defense has no chance of winning in this. Zero. Zilch. Nada. None!"
 * Like if they weren't similar enough, Trixie's "opening statement" is quite similar to one of Franziska's own in case 3 of Justice For All.

"Phoenix: Double Rainbow Dash? Pinkie: All the way! That would be so intense!"
 * Phoenix comments that ponies controlling the weather sounds like a twist taken straight from a Twilight Zone episode.
 * The scene with Rainbow Dash's "embarrassing photo" may have been a reference to a similar scene in Disgaea Hour of Darkness. One of the ponies even quotes Flonne, more or less.
 * The names of Fluttershy's flies are those of characters from That '70s Show.
 * The Judge's "OBJECTION OVERRULED!" may be a reference to his appearance in Ultimate Marvel Vs. Capcom 3.
 * Rainbow's desperate words when Phoenix meets her again in the detention center are reminiscent of Larry Butz's during Phoenix's first trial, right down to "There's nothing left for me in the world!/Equestria!"
 * Both Pinkie and Rarity have Motor Mouth moments reminiscent of Oldbag's.
 * Just after Pinkie Pie opens Ace's room using the key, she proclaims "Pinkie Pie, master of unlocking!"
 * Pinkie reminds Phoenix that her name isn't Shirley.
 * Pinkie Pie's guesses for what they'll find in Ace's hotel room include a magical stone, a secret chamber, a prisoner, a cup, and something Phoenix ordered.
 * Pinkie briefly slips into Cupcakes mode during a conversation about ladders and stepladders and cupcakes and muffins, that Pinkie Pie suddenly derails into a comparison between saws and hacksaws.
 * A list of several names includes names like Leroy Wingkons and Alucard.
 * Sonata is named after the Ludwig Van Beethoven play Moonlight Sonata.
 * Derpy, after bringing up Phoenix not knowing pegasi could move clouds, says "Oh how I laughed and laughed!" Phoenix's response is to think "Except I wasn't laughing...". This is almost a word-for-word recreation of part of the lyrics from Portal 2's ending song, Want You Gone.
 * Pinkie suggests that there are possibly two Rainbow Dashes, resulting in this double rainbow reference:


 * Pinkie then suggests that this twin's name is Wob Niar, mirroring Maya's theory about a fake Phoenix Wright named Xin Eohp in Trials and Tribulations.
 * Pinkie Pie's insistence that Phoenix shouldn't use Derpy's "offensive name" - even though Derpy introduced herself without problems - is an allusion to the unfortunate "Derpygate" conflict, where the issue of her name and original voice being removed from later broadcasts of the only episode she spoke in caused great conflict within the fandom.
 * When Derpy is curious why Phoenix avoids addressing her by name, his excuse is that "I really like your mane."
 * Phoenix's first thought about Rarity is calling her a "marshmallow pony" (a Memetic Mutation from an "A Dog and Pony Show" perspective shot).
 * Apparently, Rarity's middle name is Tabitha.
 * Rarity gives a shout out to the brony community in episode three, saying she "tried to love and tolerate" a crying child who was driving her nuts. A common brony response to an anti-brony is "I'm going to love and tolerate the shit out of you!"
 * Rarity's pen rant has a very similar vibe to James Rolfe's You Know What's Bullshit series, who also made a video complaining about the same exact thing.
 * Rarity brings up a fashion idea for Phoenix's suit that sounds pretty close to Redd White's suit from the first Ace Attorney.
 * The jokes about Phoenix's "hedgehog hair" lampshade his similar hairstyle to that of a certain anthropomorphic hedgehog.
