Luann/YMMV

Alternate Character Interpretation: Is Toni Daytona simply a Shallow Love Interest for Brad or is she a Broken Bird who has absolutely no idea what she wants (Hence her seriously mixed signals towards Brad and her dogged defense of the indefensible Dirk)?
- TJ. He is always smiling whenever we see him, he's shown to be charismatic (Talking Luann's family into letting him move in with Brad and in their house when he accidentally lit it on fire, talking Brad's dad into okaying a car trip), and has been shown to concoct sometimes rude schemes to get money. However; his parents were never mentioned, and a 2008 strip very heavily implies that he suffers from Parental Abandonment. It's easy to interpret that he's a rare male example of a Stepford Smiler who has to resort to scams or unethical business practices to get by.
Ambiguously Brown: Miguel; although he's stated to be spanish. Other colourized strips show TJ as being Ambiguously Brown, but it's later averted when he explains his parents were Italian and South American - it's entirely possible for both his parents to have been brown. (If the italian half was Sicilian.)
Art Evolution: Especially evident if you view it on Gocomics.
Complete Monster: Toni's boyfriend, Dirk, is portrayed as basically a 100% non-sympathetic piece of garbage during the entire course of his appearances, to ridiculous extent. Yes, Brad is supposed to be the heroic savior and get the girl, but COME ON- the guy's basically a 'roid addict, jealous rage-aholic who disrespects his girlfriend in front of others, and ends up wrecking her car and not paying for it, then complains about the hassle of picking her up. There is literally supposed to be no point we're not supposed to cheer for only Brad.
- Up until his return in 2010, Dirk had exactly one Pet the Dog moment. It was in a flashback where Toni tells Brad how she ended up going out with him in the first place. Her car broke down. He was nice enough to push it out of traffic for her and then wait with her at the mechanic to make sure she wouldn't be stranded there.
Ambiguously Gay: TJ. The guy's well-dressed and a good cook. We've never seen him with a girlfriend. Josh's commentary on Comics Curmedgeon occasionally lampshades this.
- Also, for a brief period, Aaron Hill. He seemed oblivious to Luann's and Tiffany's attraction to him. Evans was originally going to make Aaron come out of the closet, but backed out.
Crowning Moment of Awesome: Toni taking exactly zero shit from Brad's predatory boss Ann Eiffel ("You touch me again, Miss Eiffel, and I'll give you an eye full of my fist").
- Too bad Ann responds by firing Brad.
