This video works on so many levels!
For the layperson, watching this car decorated with funny-looking (not a pun) guys drive around a track with strange Japanese music playing might be worth a laugh, but those knowledgeable on the whole Kuso Miso Technique Japanese internet meme may think it's even more funny.
In this video, a Kuso Miso-themed car races around the track in the Xbox 360 title Forza Motorsport 2, a game which lets players customize auto paint jobs. This silly car eventually gets *cough* rear ended, and spins out of control, much like the use of this internet meme.
If you're still a newb and would like to know more about Kuso Miso Technique and all of its "ass pillows," park benches, and yaranaika, the Wikipedia entry (seriously!) actually does a pretty good job of explaining some of the background, although it will never get close to covering how crazy things have become as of late. If you're still *cough* curious after this, you can browse this gallery of "inspired" art as well.
