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 Rule of Perception
applied to surprise.
- Lauchlan of Mix Beer With Liquor And You Will Get Sicker 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 Isaac Asimov's robot novels, Elijah Baley dramatically stutters Daneel's name in the first and second books. In The Caves of Steel, 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.
- The girl who played Miranda on Lizzie McGuire did this in what seemed like every other line.
- Gaius Baltar does this constantly on Battlestar Galactica. Unusual in that he's the only character who does so.
- SHODAN from System Shock, resembling a sound card malfunction. It probably is a sound card malfunction.
- Almost everyone in the Ace Attorney series does this at one point or another.
- Tower of God:
Rachel: Wa-Wait a minute! *CRASH* Co-come in, Koon.
- Girl Genius: Castle Heterodyne personality in a mechanical humanoid body after "Unstoppable Higgs" kicked it a few times.
- Gunnerkrigg Court 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.
- In El Goonish Shive, Tony stutters his name when confronted with Grace in Tedd's form without Tedd's glasses to hide Tedd's feminine eyes.
- Celina's imp in Imp lapses into this when he's nervous, but other characters stammer on occasion.
- Done Up to Eleven in three SML Movies. And I mean three times.
- In "Bowser's Video Game", Bowser tells Chef PeePee about the new Charleyyy and Friends: the Video Game by starting his quote with this:
Bowser: CH-CH-CH-CH-CH-CH, CH-CH-CH-CHARLEYYY! AND FRIENDS! THE VIDEO GAME! IT'S ON STORES!!!
- He does it again in "Mother's Day" upon hearing the new Charleyyy and Friends DVD box set being released.
Bowser: CHCHCHCH! CH-CH-CHCHCH! CHCHCHCH! CH-CH-CH-CHARLEYYY AND FRIENDS BOX SET?! FOR ONLY 10 DOLLARS?!?!
- Bowser Junior in "Bowser Junior Goes To Disney World! Part 1".
Bowser Jr.: D-D-D-D-D! D-D-D-D-D! D-DOOFY THE DRAGON CEREAL!!!
