On one hand, it is exaggerated, since the actual sentence "I didn't do it!" is used only in "The Pilot." On the other hand, it is downplayed, since, even though the sentence is no more used, all the episodes maintain the structure that can refer to the title.
Interestingly, in "In the Doghouse with the White House" and "Twin It to Win It," the sentence "I didn't do it" is mentioned by Delia.
Artistic Title: The opening sequence even includes interesting pictures that are not from the show's universe, but taken by the cast themselves.
Babysitter from Hell: Downplayed with Mrs. Klasby from "The Pilot," who is not mean, just a cranky lady who seems to dislike Lindy and Logan for some reason. Although Deputy Doug said she used to make him rub her feet when he was a kid.
Played Straight several times as well, such as in "If It Tastes Like a Brussels Sprout" where Logan calls out everyone for being mean to Lindy after her lunch menu changes were poorly received (despite not liking them himself) and "Now Museum, Now You Don't" were he takes the blame for something she did (despite playing no part in the events what so ever for a change) costing him his job at the museum, simply because he knows she deserves hers more.
Also, Haley's brother in "Phone Challenge," who wants to teach Logan a lesson after thinking he made a fool of her.
In "Dance Fever," Logan's suit advertises Fireman Freddy's Spaghetti Station.
In "In the Doghouse with the White House," it's shown that the friends had been recorded and some scenes from "The New Guy" and "Dear High School Self" are used as evidences that they have been spying the president.
Casual Danger Dialogue: In "Dear High School Self," Delia likes to taunt Garrett even if they are trapped in a trash room with no way out.
Double Standard: Abuse, Female on Male: In the episode "Earth Boys Are Icky," Logan's first girlfriend, Danica, tells them they have to keep their relationship a secret so her scary, overprotective father, who also happens to be the new strict assistant principle, won't find out. Danica is sweet to Logan when they're alone, but verbally and physically abusive when they're around other people. When Logan does try to break up with Danica for how she treats him, she blackmails him into staying with her by threatening to tell her father that Logan broke her heart. By the end of the episode, Logan tells Danica's dad that they're going out, and he ends up being okay with it, presumably putting Danica's abuse to an end. But still, the audience wouldn't be laughing as much if that was a girl having her first boyfriend yell at, beat up on, and berate them in public, even if it was just for show.
Dumb Blond: Though not all the time, Logan has his moments.
Outright averted with Lindy, who's the closest to being a Brainy Brunette and would be this if not for her hair color (she's easily the smartest of the whole group, even edging out Jasmine).
The Dreaded: In "Fireman Freddy's Spaghetti Station," Flamey the Dog to Jasmine.
Epic Fail: In "If It Tastes Like a Brussels Sprout," the friends are showing their product ("Happy Time Flavor Changing Yum Yum Spray," a spray that improves the flavor of vegetables) on TV. Lindy, Jasmine, Garrett and Delia start feeling sick from it and vomit blue stuff at Logan.
Enfant Terrible: Kyle from "Fireman Freddy's Spaghetti Station." He was held in fourth grade because he stole a teacher's car.
In the pilot, Seth suggests that Logan and Garrett sit with the other freshmans, on the table that is right under the food vent and Logan replies, saying they are a special kind of freshman. The scene cuts to them sitting on that table.
In "Dear High School Self":
Jasmine: Well, I think we all know what we have to do.
Garrett: If it mean going anywhere near that garbage room, we most certainly do not!
[Cuts to Logan, Jasmine and Garrett entering the trash room, much to his dismay.]
"In the Doghouse with the White House," specially, had the interrogators to show photos and clips from earlier in the episode (or even earlier episodes) are believed to prove that the gang was spying on the president.
Missing Trailer Scene: The promo for "Lindy-licious" shows a scene with Logan laying on the couch using a long straw to take a sip of a smoothie, which isn't in the episode.
My Card: Senator Snell to Logan in "In the Doghouse with the White House".
My Eyes Are Up Here: Male version. Said by Delia's "date" (a young boy) in "Phone Challenge." Not less radar-y however, considering she was looking under the table.
My Greatest Failure: The plot of "Dear High School Self" stems from Lindy's regret over the fact that her letter included a wish that she would have better friends in high school. She spends most of the episode trying to cover it up and telling her friends how much she loves them.
Negative Continuity: Young Logan is played by two different actors in the first two episodes (Jacob Johnson in the first and Max Page in the ones after this one). Eight years-old Lindy also wears glasses in one episode, and doesn't in the others.
Possibly averted since Lindy might have gotten contacts in between flashbacks.
In the episode "Earth Boys Are Icky," Logan gets his first girlfriend. Then, in the very next episode, "Lindy Nose Best," Jasmine tells him that the girl he likes isn't into him because he's never had a girlfriend before. The girl he began dating just an episode ago is never mentioned.
Logan: Yeah, too bad we're grounded for the next six weeks.
Delia: My parents kept me in the basement once, too.
Lindy: Delia, we're allowed to go upstairs.
Delia: Yeah, so was I!
Nose Nuggets: In a Cutaway Gag seen in "Lindy-Licious," Logan sneezes and cover his hands on snot. Then he wipes it on a pillow.
Odd Couple: Logan is the opposite of both his twin sister Lindy and his best friend Garrett. While Lindy is book smart, Logan is book dumb. While Garrett is anxious and timid, Logan is very chill and laid-back.
Oh Crap: In "The New Guy," the five friends jump off an airplane and Garrett's parachute "breaks down."
Lindy: Okay, Delia. I know you're upset but that kind of language is not necessary!
People Puppets: In "The Pilot," Jasmine and Delia move a sleeping Mrs. Klasby's arms, Garrett moves her head, while Lindy does her voice in order to keep Deputy Doug from stopping the party and calling the cops.
Secret Relationship: Logan and Danica in "It Came From Canada," and exaggerated, since they don't want anyone to know they are dating (but they have a good reason for it). However, it is exaggerated mostly from Danica's part, since she shows hatred of Logan when someone sees them together.
Slow No: Logan when his cell phone flies off his hands in "Phone Challenge."
Smart Ball: The voice of reason of the group tends to switch between Jasmine and Lindy. This is actually played with with Garret, who is consistently shown to understand his friends' flaws while being oblivious hisown.
So Proud of You: Played for Laughs in "Snow Problem." Jasmine is proud of Lindy because she started crushing Dash, the snowboarding instructor, even after she said they weren't going snowboarding to see guys.
Delia: And how much fun did you have getting here?
Why Did It Have to Be Snakes?: Invoked. Towards the end of "The New Guy," the gang finds out Tom is really afraid of heights. Their plan to make him leave them? Pretend they love skydiving and they always do it!
