- Badass Decay: Rosie O'Gravy, dedicated cop and a true badass in her own right, suffered from this horribly as she got downsized into starring in segments featuring her niece Dot, cutting her out of the major stories.
- Bizarro Episode: "In Your Dreams", where Eliot manages to fall asleep and then the whole episode goes to the dogs.
- Ensemble Dark Horse: Mad Dog.
- Fridge Logic: While applicable to Rule of Funny, the setup of both worlds leads to some questions. Like how could there be a postal service in a world where virtually every dog will attack a mailman? And then you have things like the instinct to chase cars, yet they manage to drive them. But again, Rule of Funny comes into play.
- Heartwarming Moments: Eliot, after spending most of "Howl the Conquering Hero" trying to get Artie to see him as a hero, decides that Terri deserves that title more than he does, and convinces Artie to rewrite his school paper to reflect that. At the end of the episode, Eliot calls his own mother.
- Mr. Fanservice: When In-Universe Executive Meddling turned Ace into a Superman expy, complete with a ridiculously top-heavy hyper muscular build.
- Nightmare Fuel: Screwie Louie initially comes off as just a paranoid nutjob assuming the screws are out to get him. But then Ace encounters him and he's a deranged piece of work.
- The Scrappy:
- Rosie's little niece Dot who virtually does nothing but constantly ask "Why?"
- Eddie can be one at times too, beyond the episode where he was intentionally one. It's the constant "It's a well-known fact..." comments.
- Tear Jerker: The ending of "Ya Gotta Have Hart", when, after all his attempts to get a new job after being fired, it looks like Elliot will have to give up drawing Ace Hart, thus condemning the character to "death". The fact that Ace encourages him to do so makes it even more heartbreaking, as he can't exist unless he has a job in a cartoon, meaning he's effectively committing a Heroic Sacrifice for Elliot's sake. Luckily, there's a happy ending when Elliot is rehired.
- They Changed It, Now It Sucks!: The format went from less emphasis on Ace and company to interrupting the story with short vignettes with an incarcerated Bugsy Vile reading short stories, Rosie and her little niece out and about, or the adventures of Yves and Stephen. Eliot, too, got a makeover, with a hip new wardrobe.
