While looking through the Stuff section of the Wiki, I noticed a lot of references to a "fourth wall break." What exsactly is a "fourth wall break?"
In fact, what is a regular wall break?

Fourth Wall Breaks.

yeah i was wondering about that myself..
EDIT: if there is a breaking of the fourth wall, what are the first, second, and third walls?

The 4th wall is the imaginary wall between the actors and the audience on a stage.

The other three walls don't always exist, either, but they're considered the other three edges of a stage.
