Professor Farnsworth: You killed me! You killed me! Leela: Oh, what have I done? Professor Farnsworth: Didn't I just tell you? You killed me!
From "Crimes of the Hot"
Zoidberg: Strange. Why would Nixon, an awkward, uncomfortable man, suddenly throw a party, one of the most social events imaginable! (Snaps claw.) It's a trap, is why! They're going to deactivate all the robots!... I don't hear any gasping. Leela: We already figured that out.
Toph: Wait. It's a trap! Katara: Really? No kidding. Is that why we're sitting in a wooden cage right now? Gee, how'd you figure out it was a trap? Toph: Not for us, Katara. We're the bait. He wants Aang.
Played straight with Zuko's completely sincere declaration that:
Zuko: Doing nothing is a waste of time!
Katara: Haru not being able to Earthbend is like me not being able to Waterbend!
Hakoda: Everything okay?
Katara: We're fine, dad.
Hakoda: [Offering his hand to Aang] I'm Hakoda. Katara, and Sokka's father.
Katara: He knows who you are. I just called you "dad," didn't I?
Flash in Justice League after seeing the stuffed T-Rex in the Batcave:
Flash: "That's a giant dinosaur!"
Alfred: "And here I thought Batman was the detective."
Oh, boy. Transformers Armada. These kids probably had a lot to do with the Transformers fandom's dislike of human characters in general. A great deal of the time, their role in an episode was to spend half an hour giving statements like this:
Optimus: [Gets hit, falls down]
Alexis, [to Rad and Carlos, who are standing right next to her and watching the same fight] Oh, no! You guys, Optimus is down!
Rad: Oh, no!
And then Transformers Energon came along. Mostly it was due to an incomplete translation, though. Time would often be filled with Optimus saying to people who probably have some idea as to why they came to some dangerous place locked and loaded, "Remember, our mission is to protect the planet/Energon/injured character." Also, the first third or so of the series consists of episodes in which bad guys will steal a cache of Energon that the good guys just discovered. Every single time, someone (maybe more than one someone) will say "They're after our Energon!" Similarly, the bad guys would talk about their plan and say "We need more Energon!" as if they'd just come to the conclusion. In fact, all of the repetitive dialogue that plagues the series is delivered as if it's something that's just dawned on the person who has said it twice already.
The line from an episode of South Park, which Randy delivered like it was a huge revelation.
Randy: If we're still alive in the morning, then we'll know that we aren't dead.
The Coon and Friends saga has an actual super hero, Captain Hindsight, who arrives at the scenes of disasters to point out that the accident could have been prevented and then leaves. Usually the rescue workers then pack up and leave as well.
Roger: Yes, Hayley, I understand things that happen around me.
And in another episode:
Steve: It's the last clue!
Stan: DUH! REALLY?! Sorry, it's been a really long night.
From "Toy Whorey", when the wheels from Stan's SUV have been stolen
A guy in a car: You can't drive with no wheels.
Stan: Thank you, genius.
Timon and Pumba The Series — Timon and Pumba volunteer for a circus act and must follow orders from an obviously psychotic clown who puts them in ever more dangerous predicaments. After avoiding death numerous times, Pumba makes this comment.
Pumba: "What I still don't know is, why is he called Mr. Meanie?"
One episode of The Simpsons had Homer attempting to play "Horse Whisperer". His advice? "When the race starts, run real fast!"
And one can't forget, Ralph Wiggum's "My cat's breath smells like cat food."
Ralph Wiggum is, naturally, a goldmine of these. This is the man who brought us "Fun toys are fun!"
Another Ralph gem: "All my friends have birthdays this year"
Dr. Marvin Monroe proposed an experiment wherein he would raise a baby to adulthood in a sealed box, providing it only with basic nutrition, along with the occasional icy shower or electric shock. His theory: "The subject will be socially malajusted, and will harbor a deep resentment towards me".
There was also a scene in the episode "Homer vs. Dignity": When Homer in the panda suit is repeatedly shocked with a cattle prod, Lisa exclaims, "Something's wrong! Terribly wrong!" No, really?
"Wait a minute... THAT'S not the wallet inspector..."
In one episode, Homer's own brain has to remind him "Money can be exchanged for goods and services."
Marge: "Cannons are designed to hurt."
Marge: "Maybe [what's in your hair] is just shampoo. That washes right out."
After Lisa's goalkeeping results in a shining victory for her team, Marge praises her performance: "By blocking the net, I really think you helped your team!"
Bart: "What good's a credit card if you can't even use it?" As opposed to what else you'd do with it?
Don Vittorio in "Homie the Clown": "To murder a funny man of such genius would be a crime!" Although he may have meant a crime by mafia standards.
Also, a slightly subtler example from the episode "Bart's Inner Child", overlapping Exposition:
Homer: Well, here we are at the Brad Goodman lecture.
Lisa: We know, Dad.
Homer: I just thought I'd remind everybody. After all, we did agree to attend this self-help seminar.
Homer: And what are you charging for this free weekend?
Dora the Explorer and children's educational TV in general tend to state the obvious. Justified, as a lot common sense knowledge we take for granted aren't privy to many children yet.
In Teen Titans, about every time the alarm goes off, one of them says "trouble". Really? I never would have guessed.
Nightwing in Batman: Under the Red Hood partly because he likes to chat and Batman doesn't talk so much so Nightwing just states the obvious as a way to pass the time.
Also played for laughs (and dissimile) with the Black Mask:
Black Mask: "Maybe my last request was too mired in subtlety. I want this man dead. When I say dead, I mean seriously dead. Beaten, broken, his-head-mounted-on-my-wall kind of dead!" Ms. Li: "Understood. We'll be taking further precautions at every transaction-" Black Mask: "Screw that! Time he learns that this is a contact sport! We're going on offense. Rough up his business. Something big! Something loud! When he shows up to shut us down, have a party waiting for him! And when I say party, I actually mean A WHOLE LOT OF PEOPLE WHO ARE GONNA KILL HIM!" Ms. Li: [deadpan] "I figured." Black Mask: "Just being clear."
In early Super Friends episodes, Robin had a way of pointing out the obvious, usually in the form of his overtly religious catchphrase. This is the third post in a row about Robin.
Rigby: I see you have learned the ways of Death Kwon Do.
Mordecai: I see you're pretty good at pointing out things people are already aware of.
Adventure Time, "The Eyes", after the horse they've been trying to get rid of falls through their roof:
Finn: Aww! It's in our house now!
Jake: That's obvious, Finn, you don't have to point that out!
In the episode "What Was Missing":
Princess Bubblegum: It's the door of the Door Lord, Finn. We used to lock them up, but they kept breaking out. Because they're door lords.
Courage the Cowardly Dog was like this during some early episodes. Though he did this less frequently as the season went on, it contributed to the decision to limit his speaking abilities in the following seasons.
Family Guy had one episode that consisted of this:
