I've got a few this time, all from Disgaea.
"To show my appreciation, I'll only beat them half to death." - Laharl.
"The Overlord of the Netherworld died by choking on a pretzel!?" - Flonne.
"OH $*&% RUN RUN RUN...!" - Thursday.
Here's a long one, from Psychonauts.
Sheegor: I'm not going to bring you any more brains if you're going to be so mean to them!
Dr. Loboto: No matter what I do?
Sheegor: No, no matter what!
Dr. Loboto: Not even if I...
[he reaches towards the stove to turn up the heat on a pot over which he holds Mr. Pokeylope, who's Sheegor's beloved turtle, hostage]
Sheegor: No, don't!
Dr. Loboto: Not even if I cook you a little...
Sheegor: Don't, doctor! No!
Dr. Loboto: ...A little turtle soup?
Sheegor: Please, Dr. Loboto! No!
Dr. Loboto: Hm, a nice, hot turtle soup, hmm?
Sheegor: Noooo!
Dr. Loboto: Nothing better on a cold night like this than some boiling hot soup!
Sheegor: You leave Mr. Pokeylope alone!
Dr. Loboto: Oh. Okay.
[slight pause]
Dr. Loboto: Are you sure?
Sheegor: Nooo! I mean, YES!
*after some more inane conversation...*
Dr. Loboto: *talking calmly to the turtle after Sheegor leaves* When you're a dentist, you have to learn to have a sense of humor, you know. It helps to calm the patient down.
Hehehehe. .. cheese..?
