Tenacious D: The Complete Masterworks Easter Egg - Hidden Videos

Put in the second disc, the "For Psycho Fans only" DVD, and on the side of the road there are, if I recall correctly, three pictures, a cactus, a skull, and something else. You can click on them by selecting the menu item closest to it and pressing the appropriate direction. There are two TV spots advertising MTV's the "Ozbournes", and one advertising Tenacious D's album.
