Lifted straight from the pages of Infinite Jest (yeah, I’m a couple years late to the party but you should *really* read this book):

But there’s this way he drums his fingers on the table. Not even like really drumming. More like in-way between drumming and like this scratching, picking, the way you see somebody picking at dead skin. And without any kind of rhythm, see, constant and never-stopping but with no kind of rhythm you could grab onto and follow and stand. Totally like whacked, insane. Like the sounds you can imagine a girl hears in her head right before she kills her whole family because somebody took the last bit of peanut butter or something. You know what I’m saying? The sound of a fucking mind coming apart. You know what I’m saying? So yeah, yes, OK, I sort of poked him with my fork. Sort of. I could see how maybe somebody could have thought I sort of stabbed him. I offered to get the fork out, though. Let’s just say I’m ready to make amends at like anytime. For my part in it. I’m owning my part in it is what I’m saying. Can I ask am I
going to get Restricted for this? Cause I have this Overnight tomorrow that Gene he approved already in the Overnight Log. If you want to look. But I’m not trying to get out of owning my part of the, like, occurrence. If my Higher Power who I choose to call God works through you saying I’ve got some kind of punishment due, I won’t try to get out of a punishment. If I’ve got
one due, I just wanted to ask. Did I mention that I’m grateful to be here?

I might have copied this from the author’s pages, but I swear he listened in on conversations I’ve heard.
