One clue that you're going too far in your ironic humor is when you start finding the real thing funny.

I'm not actually sure that's the "real thing", at least in the sense you appear to mean it. His tone, as well as this more explicitly humourous video suggest that it's all at least a little tongue-in-cheek, although that certainly doesn't mean his message is irrelevant.

Anyway, I appreciate this post; I'll try and comment with something a little more cogent when I've got more time.
