I don't know why this all came to me, but I started thinking about the old game "Ultima II" (also here) by Lord British and Sierra Online this morning. And what came to me were all of the things that non-important NPCs would say when you talked to them.
Fighter: Ugh, me tough!
Thief: Psst, wanna buy a watch?
Wizard: Hex-a-poo, a hex on you!
Merchant: Will you buy my apples?
The guards said something too, and I can't quite remember what it was. It may have been "Move along" or something like that.
A fun game. I miss the chain of Ultima games, and the sense of wonder and Discovery as I played through them.
