one of the "top secret" file said the world is a triangle
The world cannot be a 2-Dimensional shape such as a triangle or a square.
The terms you're likely looking for are Pyramid and Cube, as if the world was 2-Dimensionally shaped, it would be flat, and people would have fallen off of the edge.
Now you know, and knowing is half the battle!
no we found out that the world is flat and wierdly shaped
I have to poop.
In a cup?
