what will the last season you buy be? i seriously doubt anyone here will buy every season of the show, give or take a couple members (You know who you are). hell, some people have already stopped at 10/11 i think.
i'm probably going to stop after season 19. I'm definitely getting 14-16, and i haven't seen 17-18 in a while. and for some reason i really enjoyed season 19. i don't plan on getting 20+, but i may rent them sometime to see if the bonus features are any good (and i mean, there are some episodes from these seasons i enjoy).
so, when is your stopping point going to be? or have you already stopped buying the dvds?
