Is there anything on the DVD that isn't on the Website?

Plenty!
-3D menus
-three new emails
-audio commentaries
-some new easter eggs in the emails
-new puppet stuff
-time-lapse of the making of the hundredth email
-puppet/live action stuff outtakes
-karaoke videos (with hidden audio tracks of the characters singing)
-mockumentary about the characters voices

That's what I remember off the top of my head. There's lots of other stuff, too.
