- "Doug's Bad Trip". The episode is actually about Doug and his family going on a road trip, but the title suggests...other things. It doesn't help that the episode takes place in the American Southwest.
- While dressing Doug up for his date with Patti, Judy says he should wear a handkerchief, "but not on the left." In the hanky code once used by the gay community, a handkerchief in the left pocket signaled that one was a "top."
- In "Doug Tips the Scales," Beebe's two-piece bikini is the same hue as her skin tone, leaving little to the imagination.
- Let's not forget about this gem of a line:Doug: The reason the lava keeps shooting up into the air is because I love you.
- In one episode, there is a scene where Doug is holding a banner that said "I (heart) head."
- The banner itself says "I (heart) headcheese" but the cheese part is cut off.
- Similarly, a Beets-themed poster in Doug's bedroom which read "I (HEART) TOFU" (a fairly obvious reference to the song "Killer Tofu") was read by one irate mother as "I (HEART) TO F.U.", as related by scenario writer Ken Scarborough.
- Skeeter also has a poster in his room: "Beat to the Beets."
- A restaurant at the mall is named "Baloney Hut," and its slogan is, "get your butt to the Baloney Hut."
- In another episode, the school lunch entree of the day is "creamed baloney burritos."
- In one episode, Mr. Bone says "Young man, I want you in my office P.D.Q... whatever that stands for." (It stands for "pretty damn quick.")
- It could mean pretty darn quick too.
- In the first episode of the Disney series, after Doug's mom makes the announcement of her pregnancy, Judy gives a thumbs up and says, "Way to go, Dad." leaving Doug confused while his dad embarrassingly explains that it's nothing.
- "Doug's New Teacher": Doug, upset that Mrs. Wingo's substitute teacher, Ms. Newberry, thinks he's a troublemaker, imagines himself profiled (and portrayed as a bulked-up delinquent clad in a T-shirt with a skull on it, brass knuckles and a headband) on an episode of Bluffington's Most Troublesome (hosted by Mr. Bone). In the reenactment, Delinquent Doug crashes the class's history lesson, begins reading to the class from a girlie magazine called "Naughty Boy," and holds up what appears to be the magazine's centerfold (we only see it from behind) as the class gasps.
- "Doug's Doodle" features a daydream segment in which Doug, as Smash Adams, tries to ply his teacher, Mrs. Wingo, with what appears to be pink champagne, in order to distract her so he can get his doodle of her back.
- In "Doug's Babysitter" when Judy's watching a foreign film, the word testicles can be heard. Although the subtitle on the screen at this moment reads "Huh"?, the next subtitle reads: "I despair of your silly, pointy stick."
- "Doug's Christmas Story" has one reference each to alcohol and tobacco: James Bond Expy Smash Adams gives Quailman and Race Canyon "two marts, stirred not shaken" and a dog in the "Very Bad Dogs" section of the pound is shown smoking.
- The opening of "Doug Meets Fentruck", a fantasy that takes place in an Old West-style bar, depicts cowboys smoking and drinking, as well as chewing tobacco and spitting into a spittoon. The only one not drinking alcohol: Doug himself, who is imbibing "Moo Moo Milk."
- "Doug Wears Tights":Miss Mimi: And... Plié! Plié! Plié!Doug: What?Miss Mimi: [irritated] Plié! Plié!Doug: No thanks. I just went before I got in these tights.[Beebe and Connie snicker]
- In "Doug's Lost Weekend," Doug refers to the aliens in a video game as "nutsuckers."
- In "Doug's Brainy Buddy," Skeeter decides not to go to college because all the students smoke.
- "Doug: Mayor for a Day" does this in the form of an Overly Prepared Gag: Doug helps save Mr. Swirly's ice cream factory by telling him to let an onslaught of chocolate chip ice cream hit their cooling fan, not only stopping their ice cream from melting but creating a batch of chocolate swirly in the process. The Mayor, who was too nervous to make the decision himself, sends Doug a thank-you care which reads "Sometimes, you just gotta let the chipsnote hit the fan!" In fact, Doug himself had earlier used that exact phrase while talking to Mr. Swirly on the telephone.
- "Doug Grows Up" from the Disney revival series has a moment that Crosses the Line Twice so badly you'll wonder how the episode ever made it past the censors. Doug decides he needs to start acting more like an adult, so one night he comes down to dinner dressed in a suit and referring to his parents by their first names. He then asks his mom what's for dinner, and proceeds to smack her ass before telling his dad he married "A real fine lady." Phil, Theda, and Judy are appropriately shocked speechless.
- There's a scene wherein Doug sees a lot of shoe commercials, and one of them shows a woman holding up a man's foot and saying, in a sultry voice "All my men wear shoes, or they wear nothing at all". Taking it even further, the foot and calf she's holding up (along with presumably the rest of the male actor's offscreen body) suddenly become nude upon her saying this. Then she recoils with disgust in response to this.
- The most blatant case of this was the episode "Doug's Minor Catastrophe" which is about a new snack called "Nick Nacks" going on sale that turns out to have unpleasant side effects similar to that of real life drugs. To help drive home the point the product ends up getting banned from stores and Roger ends up basically becoming a drug dealer by selling Nick Nacks himself.
