Jack Miles is pretty inaccurate. Even if I stick strictly to Talmud and consider Job a contemporary of Moses or even Moses himself (though no one really knows where to put Job timeline-wise), God not only spoke to Israelites, he also revealed himself in a vein similar to how he communicated with Moses way past Job's expiration date (see Samuel, David and Solomon, but also other major and minor prophets such as Isaiah, Elijah, Ezekiel, Jeremiah, and so on and so forth). So, Job definitely didn't silence anyone. Not even his human discussants. Now that's funny, indeed.

When it comes to God's boasting about Job's piety, he was not mistaken -- Job didn't budge on that front. The only comedy I see is how God must have known about the ill and arrogant nature of Job and thus let Satan have his time with him. Ingenious move, and certainly a humbling and sobering experience for Job, the Mr. Perfect.

As for Ecclesiastes and your poignant juxtaposition of its content to Genesis' "good" creation, that's really the only joke I see. But again, it's poking fun at the "unenlightened", no matter how accomplished, wise, rich, etc. they are -- in other words, without God you are nothing and nothing makes sense. Conversely, with God you can withstand anything. Even though, from a solely human perspective, it’s all futile in the end :P

Well, and assuming God shows you his majestic back and all you can see is his ass ... well, erhm, I don't know what it says about whom. Btw. God walked past Moses in that scene, so if he was watching carefully, he should also see God's dangling privates. After all, God is no omega ... or is he? :D Then again, was God naked? Beats me O_o

I dealt with rest in an article few months ago:
