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.
Alternative Character Interpretation: The entire show is this due to the fact that it is a narrative of events through the eyes of one kid writing about these events into his journal. As a result, his opinions on a person will affect how they are portrayed in each episode.
Said blog also speculates that Roger has rickets and really just wants to be friends (at the very least) with Doug, but doesn't know how to make friends.
Big Lipped Alligator Moment: Doug's Quailman fantasy in Doug's 1st Movie. Then again, it's a Doug movie, and it wouldn't be complete without Quailman.
Mr. Bone talking on the phone in "Doug Goes Hollywood" and breaking the fourth wall to tell the viewer to mind their own business.
Broken Base: Disney's Doug. It caused the fanbase to break into separate camps (not counting the ones who have seen one version, but not the other): the ones who loved the Nickelodeon version and despised Disney's version, the ones who thought Disney's version was okay but preferred Nickelodeon's version, and the ones who thought the Disney version was no different than the Nickelodeon version and actually admit to liking both.
Same with the movie. Some like it, some really don't like it.
Fanon Discontinuity: The Disney's Doug episodes don't exist in the eyes of the Nickelodeon Doug fans.
Genius Bonus: Doug's sister, Judith "Judy" Funny, has been established as a huge Shakespeare nut in several episodes. Which is why she's named after Sheakespeare's daughter, Judith Quiney (née Shakespeare). Just to drive the point home, her mother always insists on calling her "Judith".
In one Nick episode, Patty worries she got her hair cut too short. (Actually, it really looks no different, so it's essentially an Informed Flaw.) Regardless, fast-forward to the Disney years and... well, Patty didn't seem to mind her short hair then.
In the pilot episode, "Doug Can't Dance", one of the kids at the costume party is dressed like Mickey Mouse. Fast forward a few years, and the mouse owns Doug.
With him, the mouse acquires Skeeter's Quailman alter ego Silver Skeeter. Fast forward another few years, and the mouse acquires Marvel Comics and with them Silver Surfer.
Ho Yay: Roger seems almost...obsessed...with Doug.
This is ALL from "Doug's on TV."
Roger- "Oh, and Funnie, if I were you, I'd bring a saddle to school tomorrow... because the kids are gonna be RIDING YOU ALL DAY!!!"
Then there's this exchange between the two, sitting on the couch watching the burning of embarrassing tapes. Yeah, THAT has no subtext these days...
Doug- "This bowl of popcorn ain't big enough for the both of us, "Rowdy Roger."
Roger- "Watch it, 'Hoss!' I may have to rope and hogtie you. Don't forget, I've got the record!"
Doug- "Well, rooty-toot-toot to you too!"
Roger- "Well, yippie-ti-yo-ti-yay to you!"
And after an oh-so-appropriate pause, when Doug notes Roger is eating all the popcorn...
Roger- "Look, 'Hoss,' don't make me ride you around the room."
From another episode: "Looks like everybody's paired up but us, Funnie. Guess that means we're partners."
Doug even seems to imagine this as a possibility. In his imagine spots, Roger has dressed as a girl and put a love note in Doug's locker, kissed Doug on the head, and said such things as "Ooo, I think I'm in loooove. Isn't he just darling?"
Roger was the one to organize an anniversary party for Doug, and when Doug is flattered, quickly proclaims, "Yeah, uh, well, it doesn't mean we're getting married or anything..!"
After Roger gets over his rather short-lived crush on Judy, he promptly gives Doug the bunch of flowers he was carrying.
"My Fair Lady" has Roger butting in to join Doug's group and pretty much adhering to his side. He even wants to sit next to Doug on the ferris wheel, and Doug has to try pretty hard to convince him not to.
A female example: In "Doug's a Big Fat Liar", Patty goes to a dance with "Melvin", really Judy in drag. Seems innocent enough, but when the whole ruse is revealed, Patty isn't even upset! She even says "Melvin" is the best dancer at the hoedown and continues to dance with Judy throughout the rest of the episode. Also, they share Judy's room in an episode of the Disney series.
Hollywood Pudgy: Connie. While she was a bit thicker than the other girls in the Nick series, she wasn't the "wide load" she was hyped up to be. Averted in the Disney series.
Played with in an episode about Doug himself: He comes back after a couple weeks eating junk food at his grandmother's and realizes he's gained a good amount of weight. He slims down to his previous weight to avoid embarrassment at an upcoming pool party with his friends, only to still see himself as pudgy. Fortunately Judy informs him that's how he's always looked and to not worry about it. As it turns out, everyone else at the party has similar concerns about how they look in swimsuits, so initially nobody has any fun until Doug breaks the ice!
"You broke my grill!? You broke MY GRILL!? YOU BROKE MY GRILL!?"
Mis-blamed: There are a number of fans who whine about Disney's changes to the series. Actually, the only thing Disney did was buy the rights to the series (and Jumbo Pictures, the show's production company), produce it, and air it on ABC. Pretty much everyone who worked on the Nick series worked on Disney's series as well.
Doug himself appeared in a couple commercials before getting his own show. He appeared as an unnamed character in a Florida Grapejuice ad in 1988, and he and Porkchop appeared in an ad bumper for the USA Network in 1990.
Periphery Demographic: The show was pretty popular among adults, especially among parents who wanted their kids to watch it.
The Problem with Licensed Games: A game based on the Disney show was released for Game Boy Color, and featured Doug and Porkchop searching for Patti while wandering around Bluffington and doing tasks for various characters (collecting stuff to beam to aliens for the Sleech brothers or running errands for Judy, for example). Unfortunately, the whole game was an extremely dull fetch-quest, and the only action - minigames featuring Quailman - left a lot to be desired.
Seinfeld Is Unfunny: Doug was one of the very first Slice of Life animated shows, and was very influential. However, this has caused many shows to use the exact same format, making most of the tropes Doug made popular in the 1990s become cliche now.
Ship Tease: Doug's crush on Patti may not be entirely one-sided...
The scene in Judy's Big Admission where Judy's in tears because she thinks she didn't get admitted into Vole University. She really needs a hug, which Doug gives her.
They Changed It, Now It Sucks: While Disney's Doug lasted three years, some fans were simply turned off by the change. Of course, others did enjoy it (especially those who didn't have cable, or had never heard of Nickelodeon's version).
Ironically, the first episode of the Disney show had Doug suffering from this reaction to all the changes going on around him.
The cast of the Mexican Spanish dub was changed for the Disney version, too. Well, mostly.
Toy Ship: Doug and Patti, both in sixth grade at the start of the series and only just finished seventh grade in the final episode.
