if nothing else, consider this:

in how many dimensions does a typical pizza slice exist?

the answer is obvious, you say: three.  the typical pizza slice occupies length, width, and height, and therefore occupies that plane of reality so lucky to possess three dimensions.  how could it be any other way?

but wait: —

the typical pizza slice is two dimensions.  can you draw a pizza slice?  can you draw anything else?  have you *ever* been able to draw anything else your entire life?  you know why?  because you can’t draw in three dimensions

sure, it has bumps and crannies, just like a desk surface.  we accept this.  but still we call it flat.  

these are no dirst crustules.  these are peaks.  zeniths.  mountains.  of mountains.  heaping piles of spinach and cheese and jalapeno.

you ordered an extra topping.  you poor fool.  do you not know that this turns the pizza from an everest to an olympus?
