Pinkie should teach those peoples a lesson about the 4th wall XD

Counting that I studied literary genres and techniques since I was about... 14, I know most of its tricks and pull offs.

The 4th wall, as I studied it, is the imaginary "wall" that exists and separates the normal three-boxed set of the theatre from the people, and the people can see the actions that happen in there through on their world.

I've known what the "fourth wall" was since I was around eleven years old. I didn't learn it in school until I was about fourteen, but I looked it up out of curiosity before then. 

However, not a lot of my friends (aside from one) 'nor any adults I'm around know what it is. My guess is, they can't be bothered enough to care. 

I've always enjoyed 4th wall breaches, even though I never knew the term until ~3 years ago.

I've known about the 4th wall for quite a while now, even some of the cartoons I watched when I was a kid cracked the wall sometimes!
