I wanted to point out some links I found hugely useful and mind expanding. Apologies if this has been posted before (I did search for GHZM).
I've always found my eyes glazing over when trying to follow the derivation of Bell's Inequality, so I was very impressed when I saw this Sidney Coleman lecture.

He describes an experimental arrangement that greatly simplifies the situation and makes the difference between Classical Mechanics and Quantum Mechanics as stark as possible. This is based on the work of Greenberger, Horne and Zeilinger with further simplication by Mermin in this paper (PDF):

Sidney's explanation is a bit quick, so I didn't really get it until reading the paper and then going back to the video.
The rest of Coleman's talk is mindblowing as well.
