If you are old like me then you remember back when MTV showed what is called “music videos” (kids, you may need to ask your parents about them). One of the videos featured this guy in a funny hat in a grey room with a sliding floor. This video has basically been taken as-is, dubbed over in Japanese, and is now an ad for Nissin Ramen. I have no idea what they say in the ad, but I’m going to guess that it resembles the Mister Sparkle commercial from the Simpsons episode.
Thanks to Urlesque for the link.
