Portal was full of such lines, but I can't remember any word for word.
Max Payne 1 had a few good ones:
- Max says "Thank You" if you shoot out certain blaring alarms, and also if you shoot out a speaker playing elevator music.
- A conversation between a pair of enemies in one of the last levels after a long elevator ride:
Thug 1: I hate being stereotyped. I'm not a cold blooded killer; I'm a nice guy. I love my wife, I have two boys and I'm very proud of them. You just have to make ends meet. And if that means I have to shoot someone now and then... hey, it's just my job from 9 to 5.
Thug 2: Well.... not exactly from 9 to 5, but I hear ya.
Edgeworth in one of the Phoenix Wright games:
"OBJECTION!! ...I was trying to think of something to say while objecting. I didn't. Sorry."
I remember in Baten Kaitos Origins there was a woman in the first town who said "I see you've got quite a magnus deck there. Show me yours and I'll show you mine." Or something along those lines. I had a snapshot of it but I cant find it.
There's this part of Paper Mario: The Thousand Year Door (I haven't played it in 6 years so forgive me if this is dead wrong) in which a ghost comes to visit you, and it's floating back to Heaven or wherever ghosts go in Nintendo games, and then it comes back (I think because it forgot to tell you something).
"Did you find my my diary?
Yes, this is my diary. Very well, your blanket is right here.
You were very wise not to read my diary, friend... Hoo hoo hoo hooooooo... If you had read it, yo might be a spirit right now. But now I can go peacefully on from this world... Thank you so much. You will probably never meet me again in this world... Fare thee well..."
*starts ascending into heaven on a beam of light, but then quickly comes back down.
"...Well, actually, maybe not... I've been here so long, I've gotten kinda used to it... The wallpaper's so great. Maybe I'll stay here just a little while longer. I can leave, whenever, so... That's all there is to it. Hoo hoo hoo hoo hooooooo...
