Broken Base: On whether Carey was being a good parent in "Bowling" in punishing Zack for a harmless prank against Cody. Unlike an episode such as "Arthur's Big Hit", everyone was on Zack's side, and what he did was admittedly funny and didn't involve hurting anyone.
There's also to take into account the fact Carey was ruining something important to everyone just because Zack did something wrong and she could've just punished him after the game.
To add on to this, it also makes her actions here hypocritical since she did nothing when Cody locked Zack in the closet in "French 101" just to keep a French girl all for himself despite the fact that Zack was the one who laid eyes on her first, which shows a tasteless, biased case of Parental Favoritism on Carey's part.
Designated Villain: Carey calls Serge "a lying doofus" and that "her boys were right!" (for... modifying a violent video game?) before ditching him and dumping a pitcher of water on his head. Sure, Serge was condescending to the twins and lied about writing a poem for Carey, but come on!
Genius Bonus: In "Lost In Translation", Cody says in Japanese that he has a hornet nest in his pants, causing the Japanese guests to run away in fear. While most people would do the same, there's the fact they could've thought he meant the Asian Giant Hornet, which can melt flesh.
Maddie explaining to London that a shoelace tip is called an aglet may have been a one-off joke, but if you take Ashley Tisdale's other role into consideration, which had an entire episode about aglets...
Informed Wrongness: The episode "Kisses & Basketball". Apparently, we're supposed to side with Max after she became upset at Zack for dating her just to "take one for the team". This is ignoring the fact that this whole thing was actually Cody and Tapeworm's idea and Zack himself even refused right before Cody explains why Zack has to do it. The fact that Max didn't even give Cody and Tapeworm a stern lecture of this even after she knew they were the ones who talked Zack into it while Zack was the one who got the punishment (via getting sundae shoved in his face by Max) makes the former two come off as a couple of Karma Houdinis.
Acting as parents for a baby doll for a school project.
After a heart-to-heart talk about her father, London tries to buy diamond jewelry for Maddie.
"Poor Little Rich Girl":
London: "You took me in when no one else would. You like me for richer or poorer, for better or worse, in sickness and in health-" Maddie: "We're not married, London."
"Time to strip and make the beds!"
London:(starts taking off her clothes) Okay, if that's what poor people do...
Maddie: Whoa there, big girl!
In Suite Life Goes Hollywood, the Hollywood studio got Dante Basco to play London in their Show Within a Show, with their excuse being that they wanted a romance between the candy counter girl and the owner's kid. London's response?
Pretty much a majority of Carey's actions in the show seem to be the case, in particular her endless grounding of the kids over every little detail.
Nightmare Fuel: "The Ghost of Suite 613" is a genuinely creepy episode, from the graphic (for a kids' show) description of how the woman died, to Esteban's possession and Slasher Smile during the seance, and the real ghost coming back in The Stinger.
One-Scene Wonder: The episode "Loosely Ballroom" gets many, including a Dirty Old Man played by Rip Taylor, his nurse who he constantly harrases, a Toy Ship for Moseby, and Alexander (the great!), a rival for Esteban. None of them are ever seen again, nor do any of them appear in the credits when everyone else is shown dancing in the lobby.
Replacement Scrappy: Due to High School Musical, Ashley Tisdale had a reduced role in Season 3. This led to Mr. Moseby’s niece Nia being brought in as the new candy girl. You’d be hard pressed to find anyone who likes Nia.
David Blue, who would go on to star as Eli Wallace in the Syfy series Stargate Universe, appeared in the episode "Nurse Zack" as Dr. Chip Walters, the Tipton's young, inexperienced, and unprofessional staff physician.
Cole Sprouse (Cody) played Ross Gellar's son Ben in Seasons 6-8 of Friends.
The Scrappy: Sister Dominic is hated by a majority of fans for the way she treats Maddie in such a biased, unfair and condescending way simply because she prefers London due to her wealthy status. It doesn't help that London in those situations is basically a Karma Houdini as a result. The best examples of this are "Books and Birdhouse" and "Forever Plaid".
Barbara Brownstein, Cody's girlfriend who was more or less a Flat Character other than she was as smart as him. She garnered a lot of hate for the episode "Graduation" which featured her constantly stepping on Cody's foot because he jokingly would try to beat her attempts to be overly-academic.
Unintentionally Unsympathetic: Zack's behavior to Cody in the Christmas episode. Throughout the episode, Cody felt that his parents were falling in love, especially around the Christmas season due to overly analyzed assumptions, which Zack keeps putting down. While it's understandable Zack doesn't believe this parents are getting together again (along with the fact he's probably accepted the divorce better than Cody has), he comes off as very spiteful and rude to Cody over it instead of explaining to him why their parents wouldn't get back together.
What Do You Mean, It's Not Symbolic?: The Christmas episode has a couple named Mary and Joseph who couldn't get a room in the Tipton but are stuck there thanks to the snow. Later Mary goes into labor and has a child in the elevator on Christmas eve. The cast Lampshades how similar it is to the birth of Jesus. Except London, who doesn't get it.
The Woobie: Everyone has been this at one point of the show.
Zack and Bailey is very popular among older fans of the show. The fact that Cody and Bailey alternate between Sickeningly Sweethearts and fighting all of the time helps.
Woody/Addison is very popular, due to being entirely plausible, no objections against it, and being almost Canon, if Woody just had the guts to ask her out.
Foe Yay: Zack and Bailey in "Seven Seas News" akin to the movie its parody.
"Funny Aneurysm" Moment: In "The Defiant Ones," Cody tells Bailey that he lied to Miss Tutweiller, saying that he was taking care of Bailey's sprained ankle so he couldn't do his project, because he didn't want to besmirch his perfect track record and risk not getting into Yale with Bailey like the couple had planned, and instead ending up at Princeton. At the time, this is amusing, because one missed assignment isn't going to make that much of a difference, and it's not like Yale won't accept Cody, right? Fast forward to the finale, when Bailey gets into Yale, and Cody does not.
An author once wrote two stories about romances between Bailey and Jessica Ellis (who at the time was just one of two twins), then "Model Behavior" happened and Jessica and Bailey shared several Les Yay ridden scenes.
In another fanfic called 'Zoey 1803', Zack is turned into a girl named Zoey. Zack would later get a love interest played by a girl named Zoey.
In "My Oh Maya", Maya (said love interest played by Zoey) lists various drinks the smoothie bar sells. One of them is the Cherry Chiller. It was easy to miss at the time but fastforward to 2012 when McDonald's released a smoothie with a similar name.
In Maddie on Deck the episodes antagonist is a childish young prince who turns out to be a pushover, and abuses his power to get what he wants. The princes named Jeffery. Replace the first E in his name with an O and you'd think this was a Game of ThronesShout-Out if it weren't for the fact Game of Thrones aired a few years after Maddie on Deck.
In "Bon Voyage", Marcus attempts to create a "hip hopera" of his music for Broadway, which no one can take seriously. Now one of the biggest hits on Broadway ever is a hip hop opera.
Bob and Zack seemed to have a deeper relationship than just friends. Zack seemed very hurt that he had become mushy with Barbara. Of course, it was only played for laughs.
"Beauty and the Fleeced" episode combined this with a Stupid Sexy Flanders incident where at the beginning Woody (sans glasses) is apparently describing an attractive girl before Zack points out that Woody just mistook Cody for a girl.
This could also be seen as a shot at Cody's masculinity
"Ala-ka-Scram" definitely makes an argument for Zack and Woody, especially during their makeup scene.
Although only for one episode Bailey and Jessica have a ton of this with some fabricated Foe Yay (to fool Cody) included.
"The Play's the Thing" had a scene in the play where Haley frenched a mime played by Addison. While Cody ended up playing her, he originally intended for Bailey to do so.
Maya was briefly this during the beginning of Season 3, due to viewers thinking she replaced Bailey or Marcus. Speaking of which, Bailey herself was essentially this for Maddie at first (not help by the fact that she starts out as a complete Mary Sue).
Replacement Scrappy Series: Many people thought this when On Deck replaced the original.
The Scrappy: Cody during the Suite Life on Deck, for his outright Jerkass ways and how he treated Zack, London, Woody and even Bailey. Cody would act like superior to everyone else because of his intelligence, treat Zack and London like total morons, and be misogynistic towards Bailey to the point of parody. A good example of this is when Cody competes with Bailey in various sports simply to "prove his male dominance" against her, then gets pissed off when she beats him at everything, and in "Kitchen Casanova" he's blind to Bailey's feelings of resentment toward how he treats her compared to other girls in the cooking class, his reason being "[he] didn't wanna have a bias for Bailey" even though he did the same thing with the other girls toward her.
This got worse after Cody and Bailey break-up. He admits he had feelings for her the entire time in the "Twister" yet in the episode "My Sister's Keeper" he outright hits on Woody's younger sister Willa and insists on dating her, only because of her looks, then breaks up with her because she's a female Woody, while still having feelings for Bailey! It also doesn't help that he acts like a downright unlikable Jerkass toward Woody when he tries to talk him out of it all while having the episode expecting you to side with him.
Seasonal Rot: From mid-Season 2 into the first few episodes of Season 3, wherein most characters' Flanderization came to a peak, and watching the show became something akin to rubbernecking at the train wreck. Once Season 3 got off to a roll, the characters began to recover their charm and depth.
Strangled by the Red String: As mentioned above, Cody and Bailey border on this. While they do have similar interests and personalities, in nearly every episode they are a couple, they constantly fight and someone has to go out of their way to remind them what a great couple they are so they would get back together. If you need to constantly remind a couple how great they are, then they probably are not doing so good anyway. Also, when they break up, they keep mentioning the breakup, bordering on As You Know.
Fanon Discontinuity: It's much more enjoyable if you think of it as an adaptation of the series and don't try to fit it into the timeline.
The Scrappy: Bailey. She spends a good three fourths of the film doing nothing but bitching and moaning about Cody the entire time she got screentime. It doesn't help that even London and Woody grew disinterested by the 3rd scene they were shown in, and she annoys Moseby with her constant obsession with him. It doesn't help that she never takes into consideration Cody's reasoning and completely overreacts the entire time she's bitching. Needless to say its plain obnoxious. She doesn't contribute to anything until the end. leading to even more "Scrappy" moments of the Cailey shipping.
Tear Jerker: After Zack runs a submarine into the seawall in an attempt to impress a cute science assistant, leading Cody to do the same trying to stop him, Cody gets fired and kicked out of the program. That's not the real tearjerker—that comes in a subsequent scene when Cody tells Zack he hates him and states that despite being twins, they are not brothers.
Also the end. Zack finally gets the car and it's crushed by London's wardrobe crate. Makes it worse when you remember the reason why he wanted it in the first place.
