Another wacky Ronald McDonald clip from nicovideo. No words can describe this.

This is a remix of "U.N. Owen was her?" a BGM from a Japanese doujin
shoot-em-up called 'The Embodiment of the Scarlet Devil' (thanks
UnicornFire, for the correction). The game was developed by ZUN

No, I didn't make this. I just posted it here to share with those who
don't have nicovideo.jp accounts. The original link is below:
