This egg can only be found if you freeze frame your screen, and then scroll through the frames. At the when the main characters enter the helicopter and fly above the creature, where Hud looks up to sees a B2 Spirit bomber dropping bombs on the creature, wait until the monster is surrounded by smoke where it then attacks the helicopter. Once the helicopter crashes pause you DVD. Then scroll through the frames(this should be an option on your dvd remote). You will see the tape recorder start to mess up for a few moments until finally for a split second there is an image of King Kong on the empire state building swiping at a plane(not the newer King Kong but the older one). This is a very interesting egg that is worth looking at. If you can not find the button to scroll through screens I recommend you use an X Box 360(This is what i used)
