Rectangular Humanism

My brain is inalienable,

Impregnable to invasion from outer space.

I was seven years learning right from left;

I'll be seven learning right from wrong.

These truths I hold to be self-evident:

That all men were created separate,

and were endowed by their creator

With somewhat more than the other great apes

In certain various dimensions.

I suppose that makes me the humanest.
