Why So Many Guns

Because one is none.

Two is one.  But one is none, so two is none.

Three is just one plus two, which is none plus none, so three is none.

Four is just two times two, which is none times none, or none.

Five is just two plus three, (none plus none) or one (none) plus four (none).  Five is none.

And it just keeps progressing from there.

Mathematically proven!

You cannot own enough guns to have one gun.  So all that money on guns, you spent it on nothing.
