Hold on. You're defining this rock as an object that cannot be lifted by a being that can lift anything.
Such a rock doesn't exist, and better yet, couldn't exist. Thus, it means nothing, and there is no paradox.
Oh, Whetstone.
I find myself questioning your reason for posting this, since it won't exactly convert anyone or let anyone think more highly of you. However, it's hard to deny history, and you portrayed it humorously.
So you get 5.
