Celebrities, new bands, actors all end up doing Japanese commercials to sell product. Here's Bruce Willis and Arnold Schwarzenegger doing one for Kowa. Yes, they're usually all this silly. No subtitles needed.
I had the Rocket Science band do a commercial in Volume Three (though the rough draft was pretty sketchy). It was a silly one about Vodka and Halloween-themed. I'm working on volume 3 again and hope to have another chapter released here in a week or less.
