This cartoon, based on "Gracie Graves and the Kids from Room 402", is about schoolchildren and the school they attend. The main characters are, as the title suggests, the students at Room 402. Their teacher is Gracie Graves.
Ask a Stupid Question...: Polly does this in the episode called "The Election Show". Polly ends up being the only candidate in position running for school president. Just after her long and grueling debate which Ms. Graves finally steps in and declares over, in class in the next scene, Ms. Graves is about to announce the winner. Polly tells her to hurry up and announce the results because she can't take the patience anymore, and Ms. Graves responds with "What are you so nervous about? You're the only one running." With that as a fact, Polly still asks her "So, who won?", making Ms. Graves having to respond with "You."
Big Fancy House: Jordan's as revealed in "Mrs. McCoy's Baby Boy". Even her gardener's house was big enough to impress Nancy.
Butt Monkey: In a matter of speaking, Jesse Mccoy and Vinnie Nasta could consider to be. Basically because they always try to pull pranks that end up backfiring on them in the end, often making them face worse consequences for it than what they tried to evade.
Nancy Francis could also be considered to be in similar ways, but more because of how much she always ends up falling victim to Polly Mcshane. Of course, anybody under Polly is.
In cases of clumsiness, incompetence, and being tormented on and having pranks pulled on him by the kids, Principle Mr. Besser is.
On occasion, even Ms. Graves could be considered to just slightly be one. Because she often deals with the same kind of hell to a more intense degree as Mr. Besser. But she most often is by how she is treated by and through obligation has to put up with annoying kids like Polly, or even Jesse or Vinnie through their pranks, and others who come to her with complaints.
Cash Lure: One episode started with Mr. Besser falling victim to the classic dollar bill with a string prank. The prankster later placed a coin with sellotape for another prank. At the end, someone dropped a ten-dollar bill and Mr. Besser, wrongfully assuming it was another prank, didn't try to pick it up.
Double Entendre: In one episode, as a sly prank Vinnie tries to pull on Ms. Graves during art class, he draws a picture of "two mountain peaks" that we never see, but we hear that they are pink, and unlike anyone else especially Mr. Besser, Ms. Graves when first seeing them immediately gets the idea that the two pink mountain peaks are hinting at her. Her patience gets less to the point of eventually taking action as it gets circulated even to the point of going in a picture frame and being hung in the school hall dorm. There is even one point while Vinnie gets sent to the principle's office for his drawing, and right in front of Ms. Graves who gets even more annoyed with him, he makes a remark about how he was thinking of also making a painting about a bakery called "two buns." For supposing to be a kids' show, the episode this happens on (which is "By Invitation Only") appears to be the only episode where there appears to be any Double Entendre jokes involved in the content.
There may only be an exception with a potential Double Entendre joke in the episode "Bing, Bing, Bing, and a Shot" where in the doctor's office, Jesse and Mrs. Myerson briefly interact and he misunderstands what she is telling him, and whatever she was pointing out (because Jesse was holding a newspaper but basically to hide his underwear exposure), it could be considered Innocent Innuendo, or even Getting Crap Past the Radar.
Everything's Spoonier With Spoons: Polly is an immigrant who is completely obsessed with spoons. She's got a spoon collection, and makes a spoon exhibition for the science fair. She once started a spoon hospital.
Exact Words: Nancy promised not to tell anyone Jordan is wealthy. However, she didn't promise not to tell she (Nancy) has a wealthy friend.
False Reassurance: Jesse's failed attempt to cheat in an eye exam backfired forcing him to wear glasses. When he had enough of the troubles brought to him by wearing glasses he never needed, he confessed and was expecting Miss Graves to punish him. When she said it wasn't up to her, he was relieved until she pointed out his mother would punish him.
In another episode, Polly was standing in for Mr. Besser and found out a teacher wasn't technically qualified for the job. When she begged Polly not to tell Mr. Besser, Polly said there was no need to bother him. Polly fired the teacher by herself.
Fowl-Mouthed Parrot: Averted. When Jesse and Vinny taught insults to a parrot, Jesse suggested teaching curse words but that was as close as the trope came to being played in the cartoon.
In one episode, called "Squeezed Out", after her trip to Florida, Nancy asks the girls if they want to see her tan lines, even though we never see it happen.
In another episode, we hear Polly tell Nancy that she needs to be present somewhere to help hold her dress down while she does cartwheels. We never see cartwheels take place.
In the episode "Bing, Bing, Bing, and a Shot", we manage to see Jesse in his underwear, and his mother embarrasses him in front of Mrs. Myerson during that. Mrs. Myerson also says a few things to him during that scene that may be this, if not Innocent Innuendo.
Gold Digger: Mr. Besser and, as it seems, every other man who ever married his (ex) wife.
Miss Graves is also recognizably Peg Pete from the Goof Troop series. The same is true about Mrs. Myerson from one episode (which was "Bing, Bing, Bing, and a Shot") who only makes a couple of cameos and only says a few lines. From the few lines she ever does say, she is the same voice as these other characters but with a slightly different manner than how Ms. Graves sounds. They both sound completely identical to Peg Pete in the Goof Troop series, though. Just in very slightly different ways.
Also, Nancy is Velma Dinkley from the latest animated films of Scooby Doo, respectively.
Vinny is very recognizable to his voice actor during the same era who was in movies like Bean, Jack Frost, and The Other Me.
Jesse's mom's voice is definitely recognizable to a number of other real and voiced characters from other films.
The doctor who vaccinates Jesse in one episode (which was "Bing, Bing, Bing, and a Shot") is potentially recognizable to a number of real and voiced characters from other films. As a hint, he did the voice of Bando in Homeward Bound II: Lost in San Francisco.
Mr. Miller who was a pool official in one episode (which was "Squeezed Out") who made a couple of cameos is also very recognizable of someone who has been very famous for making and acting in his own spoofs. As a hint, he did the voice of Bigweld in Robots.
Innocent Innuendo: This may be the case with what Mrs. Myerson with her all time brief cameos says to Jesse when she encounters him in the doctor's office wearing nothing but his tighty whities trying to cover himself with a newspaper. It appears that she was remarking on a picture in the newspaper he was covering himself with, while he thought she was pointing out something to do with him because of what state she catches him in. Nothing is ever clarified, though, with what she was talking about and what he thought she meant concerning what she sees and having a shot.
Karma Houdini: In one episode, Vinnie wrote a paper titled "Mr. Besser the Coldhearted Liver Butcher", hoping Mr. Besser would never see it. Mr. Besser saw but failed to realize it was about him because Vinnie misspelled the surname as "Beeser".
No Fame, No Wealth, No Service: Nancy saved $200 to have a haircut at a fancy salon only to learn that, because she's not a celebrity, the salon's janitor would do the job.
Not in Front of the Parrot: Jesse and Vinny once taught a parrot to say rude things as part of a prank. Unfortunately, for them, the parrot heard them using their names while discussing ideas.
Oh Wait, This Is My Grocery List: Freddy once accidentally brought his mom's grocery list to school, rather than his homework, and didn't realize his mistake until Miss Graves started to read it out loud in front of the class.
Plagiarism In Fiction: Vinnie Nasta made a habit of presenting his big brother Tony's reports as his own but the teacher always remembers having already evaluated them back when Tony was her student. One time included a contest entry, which Vinnie checked to be sure Tony wasn't her student back then. She was a juror for the contest.
Rich Bitch: Jordan is afraid of being seen as one because of her wealth. Nancy ends up despised as one in the episode she brags about having a wealthy friend. The "bitch" part might be true.
Secretly Wealthy: In "Mrs. McCoy's Baby Boy", Nancy finds out Jordan is wealthy but doesn't let anybody know out of fear her friends would think she's a Rich Bitch if they knew.
Shout-Out: In one episode, Jesse was forced to wear glasses that actually damaged his eyesight. (He had a cheat sheet but failed to notice the doctor asked him to read the second line instead of the first one) The episode was titled "Jesse Magoo".
Spoiled Sweet: Jordan. She lives at a Big Fancy House (fancy enough to have a bowling lane and two pools - one inside and another one outside), has a butler but never shows off or belittles other people. In fact, she hides her wealth from her friends out of fear of how they'll react.
Unwanted Glasses Plot: Jessie was so afraid of needing to wear glasses he cheated on the school-sponsored eye exam and ended up forced to wear thick glasses (his family's insurance wouldn't cover anything cooler) or, as the shop called it, glasses "for the not so active". Not only he was constantly mocked by his peers but the glasses damaged his eyesight making it harder to run. He eventually broke them and faced the consequences of cheating. In the end, Vinnie had to wear a similar pair of glasses (his family's insurance wouldn't cover anything cooler either) and, to Jessie's dismay, managed to look cool with them.
