Disclaimer: Absolutely no offense to @Riley. Sorry if triggered.
And now... (music), O.K. Productions proudly presents... the Worthless Ri-ri-ri-ri-ri-ley!
My head is worth nothing, a piece of flossy wool,
My neck isn't worth anything, just, in a lant'rn, a trifle,
My chest is, with vox, a phrase that means nothing you'd care,
My abdomen is nothing more than a hair,
And my legs turned me into a noun.
If you think I am worth nothing, vote me up, not down!
