These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Suite Life of Zack and Cody
Examples Of The Suite Life of Zack and Cody
Acceptable Targets: Paris Hilton, as a means to subvert No Celebrities Were Harmed. They even mention Paris Hilton by name in several episodes. In an alternate universe she's president of the United States, and declares being fat illegal.
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.
Retroactive Recognition: 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 Ben in Seasons 6-8 of Friends.
Seasonal Rot: A notable change in quality occurred halfway through the second season.
Unfortunate Implications: When Zack tells Carrie he's only dressed as a girl as part of a scheme, her reaction is a very relieved "Oh thank goodness!" It's not entirely clear what she had in mind (gay? transgender? transvestive? just effeminate?) but either way it does not make Carrie look like a good mother.
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.
Bizarro Episode: Quite a few episodes make no sense. "Snakes on the Boat" particularly. It was meant to be a parody of Snakes on a Plane, but this was believed by some to even be unnecessary and not really serve much purpose.
"Starship Tipton" takes the cake, but it was saved for being such a campy yet loving send off of the original Star Trek series.
Creator's Pet: Cody in Season 2 into Season 3. He acts like a complete prick and still he's the center of most episodes.
Zack and Alex Russo/London and Justin/Max Russo. This was almost canon during the course of the Crossover.
Draco in Leather Pants: Cody again. Cailey fans tend to ignore the fact that he acts like a jackass or that he was obsessed with Bailey when he wasn't dating her.
Dude, Not Funny!: Cody belittling the rest of the Ivy League after not getting into Yale. Sure, the Brown joke was probably okay, but saying that one of the universities is a "glorified junior college" could come off as really insulting and makes Cody come off as a bitter, elitist prick.
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.
Hilarious in Hindsight: 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 interested 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.
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.
The recent "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.
Replacement Scrappy: Maya was briefly this during the beginning of Season 3, due to viewers thinking she replaced Bailey. Speaking of which, Bailey herself was essentially this for Maddie at first.
Replacement Scrappy Series: Many people thought this when On Deck replaced the original.
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.
Let's not forget the fact that Cody was pursuing Bailey despite already having a girlfriend.
Tear Jerker: In "London's Christmas Carol", the part with her in the future and her future self going "I'm alone" and on the verge of tears.
They Wasted a Perfectly Good Plot: Bailey dressing as a guy with only Zack knowing would have been a great plot point that could have been stretched out a few more episodes.
Unfortunate Implications: The show treats it as perfectly reasonable for Cody to cheat on Barbara to get with Bailey because...that's what people do? It makes you wonder why they just didn't retcon Barbara's existence like the Twins' love-interests in the parent show.
