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.
Alternative Character Interpretation: Kendra sits on her Rascal most of the time, but there are a few times when she's used her legs when there's food around. Is she just lazy or does the desire for food temporarily make her mobile?
Ear Worm: The theme song will stay in your head for days after you watch it.
Let's not forget "I'm talkin' 'bout Balls Deep..."
How could you forget "Frapp Attack?"
Growing the Beard: The show abandoned most of its connections to Family Guy by season two (not many cutaways, but plently of bizarre asides and Big Lipped Alligator Moment's to remind viewers that this is a Seth MacFarlane show) and grew into its own. Sadly, this was the same time that FOX fell out of love with the show and screwed it over so bad that it's now canceled.
Mr. Waterman hitting on Terry, the latter of whom doesn't see that it's sexual harassment. Cleveland even uses Mr. Waterman's crush on Terry to get a position as a cable installer and reinstate Tim the Bear's job as a telemarketer by telling Mr. Waterman risqué stories about Terry's days on the swim team.
Junior's love for his father can come off as this.
One episode has Junior sending an MMS of himself, lying naked in a flower, to his father.
Freight Train and Cleveland Jr. rolling on the grass, laughing. In the end, Jr. warily asks: "you aren't going to kiss me, are you?"
It's the Same, Now It Sucks: Some viewers don't like this show (or initially didn't like the show) because it is/was yet another cookie-cutter wacky family show by Seth MacFarlane, which is true, but The Cleveland Show did prove in its short time that it was funny without copying (much) from Family Guy.
Magnificent Bastard: Cleveland Junior's revenge on his dad in "The Curious Case of Jr. Working at The Stool".
Moral Event Horizon: After Rallo almost drowns and blackmails Cleveland for it, Cleveland dunks Rallo's head in the pooltwice just so Rallo would stop bossing him around.
On the other hand, Rallo constantly treats Cleveland like crap and blackmailing him was yet another example of him acting like an obnoxious little punk and getting away with it. While Cleveland clearly went overboard in his revenge, Rallo arguably deserved his long overdue comeuppance.
Principal Wally nearly burning Cleveland's old jersey and calling Junior a "chubby loser". Everyone gasped!
Rallo playing pranks on his family. He even got Junior kicked out of scouts.
Mr. Waterman killing his sham wife so he can run off with his gay lover and leave Cleveland to be accused of murdering him as seen on "Who Done Did It?". Fortunately, he didn't get away with it, but compare that to the early episodes where Mr. Waterman was racist against Cleveland, but it was subtle (and most of the jokes centered on Mr. Waterman being a closet homosexual and hitting on Terry, with Terry not picking up on how inappropriate his advances are).
Nausea Fuel: Coach McFall's hole in his cheek from years of chewing tobacco.
Gus the Bartender taking off his skin to put in a washer at the laundromat in "Tis the Cleveland to Be Sorry."
Cleveland eating bones in "Sex and the Biddy".
The Scrappy: It is very, very difficult not to dislike Arianna.
Squick: Coach Charles McFall, who had his right cheek removed after years of chewing tobacco.
Junior's feelings for Donna and the look-alike Roberta.
They Wasted a Perfectly Good Plot: In the season one finale, there could have been a touching scene where Donna comforts Cookie when Cleveland's father didn't show up in their second wedding.
"Who Done Did It?" could have had Mr. Waterman kill off his wife so he can be with Terry, but thanks to Terry not being shown much, this just didn't happen.
What an Idiot: Roberta's friends have no idea that Mrs. Tubbs is her mom, even though Donna talked to her like a mom right in front of them and they share the same last name. It's not made clear whether her boyfriend Federline, who has been to their home multiple times, is aware that Donna is Roberta's mom and is just playing along with Roberta's lie or he's just that dumb.
Cleveland and his friends starting their own roadside beer truck to sell to people stuck on the highway.
