Find three hidden easter eggs
In Tenacious D Masterworks, on disk two, there are three easter eggs. On the main menu, the first one can be found by highlighting the "In the Studio" option and pressing left. The second is to the right of "TV Appearances," and the third to the left of "Music Videos." One and two are ads they did for the Osbourne show in the UK, and the third is a CD promo, my personal fave.
