Easter egg: This applies to the Lost: Complete Collection box set. Insert the hidden disk into your DVD player, and then before hitting anything else, input the secret message from Jacob's ankh (left, left, up, right, down, right). An ankh should appear on screen. Selecting it will tell you how to play the Senet game included with the box set.
Easter egg: Watch the main menu on the second disk of the season 2 DVD. Let the music play through once, then press 'right'. A yellow monkey head will appear. If you click that, a rap about Naboo the Shaman will play accompanied by clips of Naboo from the show.
