An incredibly long palindrome

I think Demetri Martin wrote it.

Wow. O.K.
A still animal sits afoot. Tones I ring.
I sing (i.e. ride it, nuts open). On or off, I riff.
Uh… I, to lasses, say, "Oh aha, hah, all!"
It's tops. It is a Tao, bro, to my baby demo.
Can one poet arise so rosy?
As "D" I star. Comedy, baby. My my, a show.
Oh say "my my," baby.
Democrats? I'd say so. (Roses irate.)
Open, on a comedy baby motorboat. As "it"
I spot still a "ha hah!" ahoy. Assess a lot.
I huff, I riff, or on one post untied, I reign.
I sign. I rise, not too fast.
I slam. In all, it's a K.O. wow.
