Carrie has a brain tumorThis is evidenced by the World of Warcraft parody outside where she claims to have a "Virtual Headache.... no, no wait, it's a real one.
London doesn't know how many times her father's been marriedIn one episode, she says twelve; in a later episode, she says eight. Given her ignorance of so many other things, and that she and her father barely have a relationship, this is the most logical explanation.
London's mother wasn't Wilfred Tipton's first wifeHe's been married either twelve, fourteen, or eight times, Depending on the Writer. London's charm bracelet only has five charms, one for each stepmother. It's highly unlikely that Tipton was married six times in less than a year (it takes time to fill out all those papers), so this is much more likely.
Wilfred Tipton is immortalHe's been married numerous times (not that that couldn't happen if he was mortal). More to the point, he also founded Tipton Industries. Back in the 18th century, during the planning of the Boston Tea Party, there was already a Tipton Inn on the same spot that the Tipton hotel is currently on. And the current Tipton building has been around since at least the 1930s. London's father, if he was of average age for a father, wouldn't have been around to see to the building or creation of that new Tipton; and if the Tipton Inn was the direct precursor of Tipton Industries, then no modern mortal could have both started that and been around in the present... Maybe he's so incredibly old that it would be emotionally scarring for anyone to see his face. That's why he covers it.
Kirby was a beer delivery guy before he joined Tipton SecurityTo see the video evidence, look under on the main entry in the On Deck section under Hey, It's That Guy! Seriously, the dude looks, talks, and acts just like Kirby!
London's mother was a witch and her stupidity is actually just ignorance of the muggle worldStemming from a line about "You-know-who" in which London's immediate response was, "Lord Voldemort?" fans have theorized that this is the reason her mother is never around and why she is so ditzy and bad in school. All of her misconceptions about other people and real life don't come from her being a sheltered rich kid, but from growing up in the wizarding world.
Cody is a Goa'uldZaria was a minor Goa'uld (with the ego of a System Lord) who ruled a small dominion in South America. In the episode "Can You Dig It?", she was released from the preservation jar in which she hid since the overthrow of Ra, whereupon she possessed Bailey and attempted to reestablish her reign. When the rest of the Suite Life gang had her cornered, she pretended to return to her jar as per the Tau'ri superstitions. In reality, she possessed Cody, trying to remain incognito. Nevertheless, her genetic narcissism shines through, resulting in a neurotic, egomaniacal portrayal of her host, seen by all observers as a twisted parody of the Cody they once knew.
Tutweiler's "Cat Room" doesn't contain catsThe real reason she wanted so desperately to keep Bailey and London out of there is it contains her extensive and eclectic collection of sex toys (which is what she really buys after getting dumped.) Woody found one that had somehow made its way outside the cabin and, not knowing what it was, disassembled it to build his turkey leg rotating device.
The S.S. Tipton has its own cell tower/satellite uplinkHow else could everybody's cell phones work everywhere?
Chelsea Brimmer's parents are divorcedWhen Chelsea's dad was convicted of tax evasion, her mom divorced him and married Chelsea's equally-rich stepfather. This explains how Chelsea is still filthy rich despite her dad being in Federal prison, in which case the IRS would likely have seized his assets.
Cody abuses BaileyI thought this WMG up when I was reading the domestic violence article on The Other Wiki and got to the signs and symptoms, I realized the only part of the cycle of violence Cody and Bailey weren't outwardly showing was the violence part, and that could be chalked up to the fact it's Disney. The fact that Bailey doesn't show any signs of abuse after the (unseen) fact could be due to, as mentioned above, the fact it's Disney, or it could be due to the fact that Cody may not be abusing her physically. In other words, Cody's abusing her in one of the following ways: sexually, emotionally, verbally, economically (implausible, but not impossible), or by stalking her. He's most likely emotionally or verbally abusing her or stalking her, probably stalking. God, is there evidence that he's an intimacy-seeking stalker (or perhaps an incompetent suitor) in obsessive love.
Cody and Bailey lost their virginity together the night before "The Defiant Ones"It would take something of that magnitude to make Cody miss a homework assignment. The reason Bailey went along with the whole injury shtick, even tolerating Cody actually injuring her, was she wanted to deflect any further inquiry into the matter. The level of angst post-breakup is also consistent with having taken that step.
Bailey had sex with Moose and then with CodyThis would explain Cody's obvious discontent with her in Paris, about her "shaking her bonbons," as he probably assumed she slept with the french guy. This also goes with their "faking it" conversation, as she was probably Cody's first, seeing as he was a "geek" barerly going through puberty when the spin off started, and Bailey was already a beautiful girl. Either that, or Moose and Bailey fucked when she was in Kettle Corn after she and Cody broke up.
London is constantly held back in schoolIn "My Sister's Keeper," it is said that Zack and Cody have known London for six years. Since she was 15 at the start of The Suite Life of Zack and Cody, which was when they first met, London would currently be 21 years old. She could have been held back so much that she ended up in the same grade as Zack and Cody, but never noticed because of her stupidity.
Stephane was impaled on the Eiffel Tower at the end of "Breakup in Paris"When Zack and Woody land on the Eiffel Tower with Cody, Stephane follows suit. Zack and Woody believe that it's an "Eiffel Tower Wedgie." I, for one, found the sound effect illustrating that a bit...gruesome. Also, following Stephane's "wedgie," he can't be heard saying anything that would suit a sitcom villain like him. No, "I'll get you kids!" Nothing. Just eerie silence. Now, how could Zack and Woody mistake a horrifying death for a goofy outcome? It was nighttime. It was dark. They don't seem too bright anyway. It was an honest mistake.
Sebastian from Party On! has a tapewormHow else could he eat all that chocolate and not be severely obese?
Project Gemini will someday be uncovered...by Alphabet Soup. Their attempts to replicate the project result in Gem and Gemma. This even explains their names.
Zack have reunited with Maddie after the series finaleSince Zack and Maya didn't repair their relationship, it's undeniable that he still loves his "Sweet Thang". The graduation episode didn't say or show that Zack reunited with Maddie, but it could be a hint that he did. In fact, many Zaddie fans consider it that he had returned to Maddie after this episode, for both of them to fulfill each other's promises, despite Maddie not being able to keep her promise to Zack about the prom part. If Ashley Tisdale returned in this episode, the episode would have been a bit more better.
Getting London through school was the only reason Seven Seas High existedWilfred Tipton was at his wits' end after putting London through every private school in Boston, Catholic school, and even public school. As a last resort, he created a program for her in which she'd be in close quarters with (relatively) normal kids and thus be forced to learn social skills, and to see the world from their perspective. The "employee discount" that enabled Zack & Cody to attend was a full tuition waiver, since Tipton knew they had some influence over London. With London's graduation uncertain, and the boat failing to turn a profit, Tipton stood ready to abandon the whole enterprise. Fortunately, London rose to the occasion.
In "Family Thais" Zack and Girl of the Week Hilary had sexShe wasn't going to be around and born those of them seemed to be trying to get laid (with each's other wingmen, both who were in relationships)
Mr. Mosby is related to Jeffery from The Fresh Prince of Bel-AirTheir personalities are close enough that Mr. Mosby could easily be an Expy of him.
Cody is either gay or transgenderHe has several feminine aspects to his personality and also has no qualms about crossdressing.
The Suite Life takes place in the Stargate VerseJust too many coincidences going on. The Goa'uld connection has already been made in a previous WMG. The events of "International Date Line" could be taking place during the same time as SG-1's "Window of Opportunity" (for some reason, Cody may be experiencing all of the time loops just as O'Neill and T'elc had) which means it was just a matter of fixed time for the loop to be closed as far as Cody was concerned. Other strange events (what happened when they went into the Bermuda Triangle, etc) might be the result of stargate-related phenomena too.
Bailey also got a rejection letter from YaleShe lied to Cody because she was so sure he would get in. But when he revealed that he was also rejected, she felt so ashamed and afraid that Cody would see less for her for both the lie and apparent academic inferiority that she kept rolling with it. She said her goodbyes on the ship and stayed in New York City where she dyed her hair, invented a new backstory and a new identity for herself - "Jessie Prescott".
Cody's rejection to Yale was a mistake by admissionsHe sorts the whole thing out in the fall as he said he would do.
Bailey Pickett is going to make an appearance on JessieJust to prove they are NOT the same character.
Disney reused Cody's wardrobe as Milton Krupnick's and attempted to reuse London's wardrobe as Emma Ross'.Milton wears shorts more often than not, especially in the first two seasons, because Cody's pants would be too short on him. Otherwise they have the same style. It's known that Peyton List pointed out that Emma's original wardrobe wasn't fashionable enough for her character, and ultra-fashionable girls' clothes age faster than preppy/nerdy guys'.
Arwin missed his calling as a great scientistHe was forced to drop out of MIT and take a job as a hotel maintenance engineer in order to care for his ailing mother.
Cody Took a Level in Jerkass and became so flanderised because of his low self-esteemIt's canon that Cody has low self-esteem (as stated by himself in "Mulch Ado About Nothing" and "Goin' Bananas" and Zack says, while stating for the nth time that no one likes Cody, that "even Cody's not crazy about himself!") and is constantly told how no one likes him and how boring he is, and as a result, he threw himself even more into academia and school because as he says again in Goin' Bananas, "academics is the one place I can excel and be my own person, instead of Zack's nerdy brother!" resulting in his intelligence and nerdiness flanderisation. The Took a Level in Jerkass comes from a misguided attempt to be more like Zack, who is far more successful socially and with women despite being a sexist pig and extremely manipulative and lazy. Alternatively, he developed an attitude of "no one is nice to me, so I won't be nice to them" from constantly being told no one likes him. This also explains his obsession with Bailey, pre- and post-breakup: due to his low self-esteem and nerdiness, he became convinced that no girl would ever take an interest in him, so when someone as beautiful and charming as Bailey did, he latched onto her forcefully and doesn't let go because she symbolises the fact that he is in fact capable of having women interested in him and that someone does like him.
