Lost: The Complete Second Season Easter Egg - References to the Numbers

Insert disc seven. Select "Phase 3," and from there select the feature "Lost Connections." This feature is an interactive web of screens connecting the show's principal characters through a series of wires connecting one character's screen to another's. Begin on Jack's screen and select the top wire on the right side of Jack's screen. This will take you to Desmond's screen. Select the wire in the upper left-hand corner of his screen. This will take you to a new screen. With your remote, input the numbers 4, 8, 15, 16, 23, 42. This will cause new connection wires to branch off from the screen. Select any one to view a montage of references to a given number made during the course of the first two seasons.

At the end of the number 8 montage, a fuzzy image of a book with the title "Valenzetti Equation" appears for an instant. The top wire of the left side of the screen will return you to Desmond's screen.
