I am in a hell of spot, I started watching them last year on netflix, they have the first and second season, but no third season. So I have been DVR'ing the fourth season and so far have been able to resist watching them, but not sure how long I can hold out. I check netflix once a week to see if the third season is on...still not.
Awesome shows though, cant wait to watch them.
Another good netflix show (and they have all the seasons) that I cant get enough of is Rescue me, Dennis Leary is badazz and he has a few scenes where it is like his stand up, they let him go off, funny, and lots of truth to what he has to say.
