You Can Talk

"Leela: Nibbler you... You can talk?

Nibbler: I can do more than talk. I can pontificate."

- Futurama

The character stumbles upon a seemingly normal animal/inanimate object. Turning away from it they hear a voice addressing them. Confused, they look around to see no one but the animal/object. When they finally realize it was the animal/object that spoke they freak out and exclaim their disbelief whilst stating the obvious.

Often coupled with: "Why didn't you say anything before?"

Which is then usually replied with You Never Asked.

Anime and Manga

 * Bleach: Uryu is asking Orihime who their master will be. Orihime says that the master was standing there the whole time. Yoruichi speaks up to tell Uryu that it is "he" who will be training them. Uryu predictably freaks out at the notion of a talking cat. After regaining his composure over the issue, Uryu calmly states he can't believe that there is such a thing as a talking cat.
 * In Magical Girl Lyrical Nanoha Striker S Erio and Caro had this reaction when Zafira spoke. This is a It Was His Sled moment for the audience, who knew he could do so, but he had never spoken in front of them before, and he was spending all his time in his wolf form.
 * This happens between Captain Shiki and Dr. Indigo in the One Piece movie Strong World. Dr. Indigo tries to explain something to Shiki through charades or mime or something. When Shiki doesn't get it, Indigo just comes out and says it, and Shiki gives the reaction with much surprise. This happens more than once.
 * Mameshiba

Comics
"Loz: You can talk! Well I'll be! We've had our budgie for seven years and all it can do is whistle."
 * In Alan Moore's Skizz from 2000 AD, the characters contrive a plan to break Skizz (an extra-terrestrial who crash-landed and stranded himself on Earth) out of an RAF airbase in Birmingham, not knowing that he has been taught English by his captors. When Loz discovers this, he has the following to say,

"Father: Can you say "dada"? Come on, Marvin! Say "dada"!
 * Happens in Buck Godot Zap Gun for Hire. Buck manages "Was that... did you..." and then gives up and just looks thoroughly bemused.
 * Earlier in the series, the second appearance of the Pistol Packin' Polaris Packrat shows him brainwashed by court order into believing his Hypercompetent Sidearms, the talking pistols Smith and Wesson, are hallucinations and thus should be ignored. Eventually, they trick him into responding to them, which throws him so deep into this trope that he fails to notice Buck (who is not generally very stealthy) sneaking up from behind and clobbering him senseless.
 * In one printed Garfield story, Garfield and the other animals sense a huge storm approaching that will destroy the town. Garfield convinces the other animals that they need to warn their human families about this and that this is reason enough to reveal that they can talk. Jon and the other pet owners all react this way when their pets suddenly start talking to them, which nearly distracts them from the huge storm their pets are trying to warn them about in the first place.
 * Kicked off a week-long Out of Genre Experience (turned out to be a nightmare the father was having) in Marvin:

Marvin: (in Thought Bubble) Oh, very well...

Marvin: (out loud) Dada, papa, daddy, father, pops, pater, and my old man.

Father: Wh-wh-wha-y-y-y-you can talk?!?

Marvin: And better than you, apparently."

"Lovecraft: Ah! Look, it's attempting to communicate. No doubt the savage thing knows the language like a housepet knows its reflection in the mirror. The sense is taken in, but the process, the meaning, is lost forever.
 * Played for Laughs (well, as a joke, anyway) in Transmetropolitan: for Spider Jerusalem's first interview with presidential nominee Gary "The Smiler" Callahan, it's his sycophantic campaign manager who actually answers most of the questions, while Callahan just sits there, immobile... smiling. When Spider finally gets fed up and forces the issue, there's a long silence before Callahan extends his hand and re-introduces himself, prompting a reaction of mock horror.
 * At the beginning of Grant Morrison's Doom Patrol run, Larry Trainor's Negative Spirit suddenly begins speaking after twenty-plus years. When queried on this, he responds that he "had nothing to say." Things quickly get weirder from there...
 * HP Lovecraft is quite, er, surprised to discover that Atomic Robo (whom he has mistaken for an armored pygmy) can speak.

Robo: Yer razzin' me.

Lovecraft: See how it cobbles together a string of sounds not unlike words? Take. Us. To. Magic. Thunder. Man.

Robo: Uh-huh.

Lovecraft: Oh, back to its native grunts. I say, the poor beast is devolving before our eyes, Charles."

"Italy: Oh, there's a kitty! *picks up Germany-cat* Hi there!
 * In this Axis Powers Hetalia doujin, Germany is transformed into a cat by England. Italy is out of the room at the time, so when he returns and sees a cat in Germany's place, he goes over to it and cuddles it. When Germany-cat starts talking, this is Italy's reaction. (Warning: Slightly NSFW)

Italy: IT TALKS?!"

The young son thinks the talking cat is very cool and starts asking the kitty criminal if he is a mutant "'cause I read in this comic book once..." Tinkles mockingly replies "ohh I read this in a comic book. YOU MAKE ME SICK!"

 * In Disney's Pinocchio, how the Coachman tortures the Donkey Boys after they've transformed actually depends on whether or not they've all lost their ability to speak: those that cannot talk anymore are all sent to either the salt mines or the circus, while those that still do are all forced to stay behind at Pleasure Island where they are locked in a pen. At least the salt mines/circus would have been a kinder fate for them.
 * The Cat From Outer Space, when Jake (the cat) first reveals his telepathy:

Jake: Well, it isn't the mouse.

Frank: But your lips aren't moving! You're not... speaking.

Jake: Thought transference. Nothing exceptional where I come from."

 * A variant of that joke has the son of university professors who is seemingly retarded, the parents start spelling out things like "intellectually inferior" because they don't want him to know what they're saying, and he says "You left out an 'l'". This may be Truth in Television.
 * There's a joke about a frog asking a girl to kiss him and turn him into a prince. The girl grabs the frog instead, because "men come and go, but a talking frog is worth something!"

 * The following joke:

 * It's kind of a joke in Discworld that people always have this reaction to Gaspode, despite living in a setting where such a thing is hardly implausible.
 * It's explained in the books that adults have ideas about what "must" be real and what must not be, so their minds edit out a lot of what comes through their senses.

Brutha: Well, they might all talk. They just might not say anything when I'm there."

"Pip: You can talk! You're a talking snake!
 * Subverted in Sourcery where Rincewind meets what appears to be a very well spoken snake, but is too embarrassed to mention it.
