Well A) I don't think you understand what that expression means and B) the "most heavy-handed" Simpsons joke sure as fuck wouldn't be anything from the good pre-zombie Simpsons era. I'm sure you could just tune in to any modern new Simpsons episode and take your pick of the fuck Drumpf shit they're probably throwing at viewers now.>>105594461>Wouldn't the fact that there's airtight proof that something based entirely on faith being fake the joke itself?
No. I don't get how you and OP are getting so confused by such a simple thing here.
The joke is just:>Homer is temporarily smart from that procedure.>He incidentally disproves God while working on his flat tax plan as one of many examples during that episode demonstrating how his newfound intelligence is manifesting.>Ned has structured his entire life around God existing.>Homer's proof is airtight to the point where even Ned can't deny it's true.>There's humor in the juxtaposition of Homer's indifferent casualness in completely destroying a major worldview as some accidental byproduct of a tax proposal with Ned's extreme devotion to this worldview (for a similar example of this sort of humor, look at the Grimes episode where Homer's casual indifference towards having accidentally achieved ridiculously impressive feats like going into space as a NASA astronaut is juxtaposed with Grimes needing to put in many years of serious-minded hard work just to get what little he has).
It's not heavy-handed at all because of course you're not going to disprove God accidentally while working on a tax proposal, and therefore the creators aren't even really trying to tell you God does or doesn't exist in the first place. They're just presenting a funny and unrealistic scenario in showing how Homer's incredible "105 IQ" is playing out.
