OK BB, here you go - I think your main problem is the style of how you've written up the idea.
Look at your first para - it's all one sentence, and doesn't make sense unless the reader can get all the way through to the end. But I think you've lost everyone halfway through, so they've wandered off thinking "what was all that about, then?" Seriously - I reckon about 10% of your readers understood what that paragraph was saying.
You've even got a comma that shouldn't be there, right in the middle, because it's such a long sentence even you probably needed a break.
Apart from that, you should make it clear straight away that it's South Korea you're talking about (not "Democratic People's Republic of Korea", which isn't as familiar), and underline the fact early on that this is the Korea that makes Samsung phones and is supposed to be the friendly one. Then you've set the gag up a bit clearer, you can start on the "stupid Americans are burning Daewoos", which isn't such a bad joke.
Compare to Bonjo's Korean sub - it's so clearly and sharply laid out that you can't help understanding his point - he steers you along gently. One commenter even said they were already expecting the Easy Korea angle - this is because the whole thing is so logical, even with the craziness of "painting houses wet".
Hope that helps. On the bright side, you've got loads of crazy ideas, which is the hard part for most people. Hooray!
