Aside—a comment from my phelps YouTube video:

How the hell can someone type that? If I were drunk, high on acid, and dead, I still couldn’t accomplish a sentence(?) like that. And trust me, I can write some messed up sentences. Exhibit A—a paragraph from an e-mail I wrote a long time ago:

Ok, check this out. Esquire, right? Squire, an occupation in the medieval times [$70/ticket], right? Squirell, right? Wrong. My version has red lines. YEh, yeh, dashed ones that mark this special occasion, every one of them.

Ok this aside is too long. I should post that whole e-mail sometime.
