Halo 2 Easter Egg - Ling Ling's Head

Go into the Xbox dashboard and change the date to 7/7/2007. Then put in Halo 2 but DO NOT sign into Xbox Live, because that will correct your clock,go to the level Zanzibar then go to the beach and look at the sign that used to show the no-swimming sign, it will be different. I dont want to ruin it for you though. But go check it out it will be worth it.
