Fanboy and Chum Chum

Fanboy and Chum Chum are the titular protagonists of the critically panned 2009 Nickelodeon series, mh:terribletvshows:Fanboy & Chum Chum.

Personality
Fanboy and Chum Chum are a hyperactive duo who spend most of their free time hanging out in the local convenience store or having all sorts of wacky adventures in their house. Both of them are comic book nerds (though not as much as Oz), and get ecstatic over the slightest things.

Why They Don't Deserve Any Frosty Freezy Freezes

 * 1) They are basically little more than pale rip-offs of both SpongeBob SquarePants and Patrick Star alongside two superheroes, Mermaid Man and Barnacle Boy from SpongeBob SquarePants, with the combined worst traits of the former two characters, and with none of their intelligence, maturity, likability and charm, so much to the point that it makes both SpongeBob and Patrick's respective Season 6-8 incarnations look like way more likable, mature, comedic, intelligent and less annoying characters. In fact, if you take away everything likable from both SpongeBob and Patrick, you get both Fanboy and Chum Chum in a nutshell. Besides, they are also rip-offs of Beavis and Butt-head from the TV show of the same name, especially considering their personalities and behavior.
 * 2) They are horribly animated in cheap-quality CGI animation, to the point where they look uncanny.
 * 3) They are even poor parodies of Batman and Robin from DC Comics.
 * 4) Their names are downright laughable.
 * 5) They're a generic comic relief duo who go on wacky and crazy adventures that are troublesome up to eleven.
 * 6) Their voices are really loud, high-pitched, very annoying and squeaky; not helping is the fact that they often scream loudly most of the time.
 * 7) They provide way too much toilet and gross-out humor.
 * 8) * They have a gross habit of sticking out their underwear in front of other people.
 * 9) ** As said in the intro: "We don't care, if you don't stare, I mean look at our underwear!"
 * 10) * Chum Chum farted.
 * 11) * They swapped noses in the infamous episode "Pick A Nose".
 * 12) * Fanboy farted on Kyle after he refused to pull his finger.
 * 13) * Fanboy sneezed on his face mask, which made it hang down in green blobs of snot.
 * 14) * Chum Chum got his nose rubbed by Mr. Mufflin's smelly foot.
 * 15) * Fanboy got his head stuck in a toilet.
 * 16) Their character designs are laughably ugly. They look more like monkeys than humans and even look like they were stolen from other medias. Easily tell because they look similar to Batman and Robin (as mentioned in WTDDAFFF# 3).
 * 17) For their "superhero" costumes, why on earth do they would wear them at school, and also, why would they not take off their costumes whatsoever or who their real names are?
 * 18) They always annoy and pick on Kyle and Lenny every time they encounter them. What's worse is that they usually never get their comeuppances, which means that they're Karma Houdinis.
 * 19) They cry over things that aren’t a big deal whatsoever, like Fanboy when he forgot to give Chum Chum a present for his birthday.
 * 20) Despite the two often dressing up as superheroes, they barely ever act like actual superheroes.
 * 21) In one short, they made Kyle float in the air after forcing him to chew bubble gum and they say "bubble" three times.

Redeeming Qualities

 * 1) They did get a bit better in Season 2 (most notably in the second half), though not by much since most flaws still remain (even in the second half).
 * 2) Their friendship can be charming at times.
 * 3) Their occasional action scenes are pretty fun to watch.
 * 4) * They can be cute sometimes, especially Chum Chum.
 * 5) Some of their jokes are admittedly funny.
 * 6) They do (although rarely) get their comeuppances for their actions.
 * 7) While their voices are high pitched and somewhat squeaky, David Hornsby and Nika Futterman do some good jobs voicing them with David voicing Fanboy and Nika voicing Chum Chum.

Trivia

 * They became internet memes.
 * Their designs are based on Batman and Robin.
