I doubt this is possible. It's also not necessary since the show will get season 4 with these ratings.I know this will never happen, but could Harmon (or maybe Sony, but iunno) start a Kickstarter fund to help fund Season 4?
They wouldnt come close to raising anything significant overall, and it might come off as desperate, but it could create some good buzz for the show. They could pull it off as "hey, pay for the Season 3 DVD now and we will take that money to fund Season 4."
I would pledge $50 if it got me a copy of Season 3 on DVD as well.
Ohhhh.Digits = Fingers.
Hopefully you get the rest from there.
