FullMetal Alchemist Volume 4 Easter Egg - Hidden Previews

In a normal english episode of FullMetal Alchemist, you can see a short preview of the upcoming episode. This can also be activated by clicking on the "Episodes" title on the main menu, choosing your episode, and finally selecting the header "Preview" at the bottom of the page. There is a hidden "preview" that is in Japanese with English subtitles. I'm not even sure if they're actually Japanese prieviews or just humourous spoof previews.

Here's how to unlock them:
1.) Go to the main menu and select the "Episode" title
2.) Choose any episode
3.) Press right twice
4.) Press enter
5.) Enjoy!
