I think Darrem Charles will be calling it quits real soon. Also, Troy Alves might call it quits too. And of course Big Ron should call it quits even tho i'd love to see him come back next year and spank Jay, but i know that ain't gonna happen.
Oh, and how can I forget.....KAMALI! He should have quit a long time ago. His physical problems (no arms, wide waist, palumboism, etc.) cannot be corrected at this point and he just needs to realize that and accept it.
Gunther can't get any better than he is now, so he may want to think about his health at this point instead of trying to "improve" the impossible.
