In detail? Not "Joker does ****". I know "Joker does ****", but I'm curious about the general set-up, tone and the "why", for some reason. Details and specifics, please.

More than any other scene I've heard about, this one has caught my attention and I've been so curious about it. I've seen it mentioned in numerous reviews, with words like "shocked", "disgusted" and "stunned" used, so that really amped up my curiosity.
Feel free to place the scene/details in spoiler tags, or, better yet, simply PM me about it so we don't encounter any "I didn't want to be spoiled, but I clicked the spoiler tags anyway" controversy.
Two things:
1. This is a spoiler forum, so asking for such a thing shouldn't be any sort of violation or an unheard-of affront to anyone.
2. I'm actually asking to be "spoiled" on this one scene, so please don't take the time to post "just wait and see" or something equally unhelpful.
If I was interested in "waiting and seeing", I wouldn't be posting this simple request...

It's a serious request, and I'd really appreciate serious, helpful replies! I don't often do this, but this one scene is just scratching at my brain for some reason.
So anyone who's seen "The Dark Knight", please spill it about this "pencil trick" scene. Thanks in advance! Again, feel free to PM me if you'd prefer. Include as much detail as you can (dialogue, reaction, why it happened, who's involved, etc.).
