Equivocation Part 2

I've just remembered something I read back in 1st year considering arguments for and against God. Whether we consider God's existence contingent or necessary, it really makes no difference.

Consider George. He is a talking horse with flippers for hooves, that speaks Japanese and can recite the whole of the play "Homer" in a minute which also happens to have the property of necessary existence. Doesn't seem inconsistent, therefore George must necessarily exist.

Which brings us to an interesting topic, is existence a predicate?
