Fourth wall

The fourth wall is an imaginary wall people break all the time because they didn't read the script of the episode they were in.
==Examples==
*Wait, what's my line?
*This show is a mess. I'm leaving. (walks out the screen)
==Trivia==
*Sometimes, the fourth wall is shown on screen and shows cracking and/or breaking.
**And also, the wall will sometimes fall on the person/people who broke it.
**And rarely, the fourth wall appears again for revenge.
