My favourite thing so far in Divine Divinity:

I'm cleaning out a dungeon, killing skeletons left and right.

No biggie.

I start going down this hallway and the camera pans down to these two skeletons talking about the fact that they're not hungry because they don't have stomachs.
Then one asks why they can talk if they don't have vocal cords.
So the other one says that he doesn't know, and wonders what exactly is keeping them together since they are just skeletons after all.
The first one then says, "Ah, I don't like thinking about these things. It leads to all sorts of existential problems."

Then they fall apart :)

Hee hee.
