These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ensemble Darkhorse: Zoey, for the reason that (with the sole exception being Penny and Sticky) she's the only character on the show who's not a raging jerkass.
She does admittedly turn on Penny in "Twins to Tweens", though you could chalk that up to Al Roker's magic manipulating things
Esoteric Happy Ending: "The Legend of Johnny Lovely". An actual boy named Johnny Lovely is suspended from school after dancing with Penny. She then leads a wild goose chase in search of him that ends at the intersection of Johnny Avenue and Lovely Lane. Penny then concludes thatJohnny is just a legend and that he may be out there somewhere.
"Funny Aneurysm" Moment: In a 2003 episode, Penny is watching a football game and says that Michael Vick is the man. Then in 2007...
The episode with Kobe Bryant also became a tad uncomfortable to watch after his highly publicized court case.
Jerkass Woobie: Dijonay in the episode "Surf and Turf" when Sticky refuses to kiss her in front of a lot of people.
Suga Mama in a few episodes.
The Scrappy: Dijonay and Lacienega are this, due to how they treat Penny. Although Lacienega became a Lovable Alpha Bitch, she still slips back to being a jerkass and constantly bullies and belittles Penny and other characters. Wizard Kelly counts as well for his callousness and jerkass attitude. He also gains pleasure from bullying Oscar for his failure to win the basketball game he played against him.
Ironically, the TV movie has Penny continually refer to Zoey as her best friend...I guess she dumped Dijonay and Lacienega during the Time Skip.
Viewer Gender Confusion: Some viewers mistook BeBe for a girl up until the episode where he and CeCe were turned into teens.
Wheelchair Woobie: Subverted. Penny dates a boy in a wheelchair (voiced by Shia LaBeouf) because he made her feel bad for him, only for her to realize he's a Jerkass who exploits his handicap to get what he wants.
Not to mention, the Double Standard - Penny and her friends are suspended because they were (wrongly) suspected of having been behind the vandalism. When the true vandal is caught and is revealed to be in a wheelchair, all he has to do is apologize. Naturally, this is heavily lampshaded and called out on.
The Woobie: Penny. She usually suffers bad luck from either her friends or her family.
Zoey, on the episode "Penny Potter" when she feels that nobody notices her.
