is the 4th wall when the characters talk to the audience, or is it when they are aware that they are in a comic?
I have one with two persons talking about the comic characters not being the real people while these two are being drawn by the comic character (reverse 4th wall, I guess)
Also I'm currently working on another one where the pets are angry at the humans for not being even mentioned in the comic title, or in any panel, not even as a background.
not sure if that counts.
