Well, then it begs the question. Is George's Dad gay? If he was originally intended as gay and indeed that was hinted at during the pilot, is the real George's dad the gay one as initially portrayed, or the straight one as it was eventually switched to?

The man does like Shakespeare's sonnets.

I don't really have a preference for him to be either, except that if Fuller had him as gay to begin with, he should have stayed gay.
