Characters in some works, particularly anime, tend to stutter whenever even slightly surprised.

(Alice, Bob's wife, returns home early, without going shopping)
Bob: A... Alice! You're early!

Can also be written as "A-Alice! You're early."

Probably happens due to RuleOfPerception applied to surprise.

!!Examples:

* ''CodeGeass''.
* The girl who played Miranda on ''Series/LizzieMcGuire'' did this in what seemed like every other line.
* ''Creator/SpikeLee'''s ''DoTheRightThing'' has one character that stutters a lot.
* SHODAN from ''VideoGame/SystemShock'', resembling a sound card malfunction. It probably ''is'' a sound card malfunction.
** [[FanWank She seems far too vain to permit malfunctioning hardware in her system. It's likely that any of the thousands of threads she's processing briefly require more cycles for a computation, and she allocates just enough from voice synthesis to cause a noticeable stutter without halting her speech]].
* ''TowerOfGod'':
---> '''Rachel''': Wa-Wait a minute! *CRASH* Co-come in, Koon.
* [[http://www.journalfen.net/community/fandom_wank/970081.html "You cannot deny the emotional impact of the stutter-typing!"]]
* Almost everyone in the ''VisualNovel/AceAttorney'' series does this at one point or another.
* ''Webcomic/GirlGenius'': [[spoiler:Castle Heterodyne personality]] in a mechanical humanoid body after "Unstoppable Higgs" [[AreTheseWiresImportant kicked it a few times]].
* Gaius Baltar does this constantly on ''Series/{{Battlestar Galactica|Reimagined}}''. Unusual in that he's the only character who does so.
* ''Webcomic/GunnerkriggCourt'' uses this. In a flashback, the main protagonist's now-deceased mother implies she has fallen in love with quick-witted fox Renard, resulting in his use of this trope before she leaves him hanging with a mischievous smile. Happens again years later when, after returning to the Court, Surma's daughter Antimony says she'd let Renard return to the forest if he wanted (him not being able to escape so long as she didn't allow it, being the only reason he's not trapped in a large cell being tortured) and he repeats this action while telling her not to ask that of him, going on to say that the love he had for Surma, while not what he had once believed it to be, hadn't gone away and muses that someone has to be around to protect Antimony.
* Lauchlan of Literature/MixBeerWithLiquorAndYouWillGetSicker commonly speaks with a stutter. However, this is justified as he's characterized as an extremely anxious and neurotic character. When he's angry or attempting to be serious he can usually repress it, but it takes some concentration.
* In Creator/IsaacAsimov's [[Literature.TheCavesOfSteel robot novels]], Elijah Baley dramatically stutters Daneel's name in the first and second books. In ''Literature/TheCavesOfSteel'', the stutter stems from Baley's initial discomfort in talking to a humanoid robot and calling it by the familiar name; but in ''The Naked Sun'' his "D-daneel" is pure surprise and pleasure at seeing Daneel again.
* In ''Webcomic/ElGoonishShive'', Tony [[http://www.egscomics.com/?date=2003-05-21 stutters his name]] when confronted with Grace in Tedd's form without Tedd's glasses to hide Tedd's feminine eyes.
* Admit it, [[TruthInTelevision you've done this once or twice when surprised.]]
