And now that you've explained the "joke," that means that it wasn't told correctly, because if it was, no explanation would be needed.You're in the minority here.
I hate to explain the joke, but it seems I have to do it: such builds are funny BECAUSE they work mechanically, according to RAW. Common sense not much, but Rules As Written indeed. Creating a homebrew class with a feature to Become A God at 1st level is lame and not funny. Creating a build that lets you Become A God at 1st level (if you're a kobold) and WORKS within the RAW, even if no sane DM would allow you to pull that off, is hilarious.
