Saw Uncut Edition Easter Egg - Cast and Crew on Billie the Puppet

Stick in the second DVD. Go to the "Dissection" menu. Hilight "Menu" and press right on your DVD remote. The jigsaw killer's puppet should appear. Now press either enter or play, whichever works for you to get it to play.
What should be playing is a featurette which contains interviews with the cast and crew talking about 'Billie the Puppet', which is the jigsaw killer's puppet that you see in the movie. They talk about the puppet as if it's a real person. It's entertaining but I didn't really think it was all that funny because I've seen similar acts before.
