Repost from the Archive, to make clearer why they're the only examples provided: Bob And George and One Over Zero aren't in any way special; they're listed purely for illumination, rather than specialness. If you can find a better pair of examples that theoretically go in the same region of this scale, but one is clearly further down the scale than the other, go ahead and replace them.

No examples for 'Beyond Fourth Wall'? Without a more solid definition, people are just going to use it as a hyperbole for other categories.
