I haven't seen it since the shy big guy/kid, can't remember his name, slept with Grey...and a few episodes after that (think the last one I saw was the other blonde girl stuck with her hand in someone's body holding an explosive device). So I guess just the first season or so. I used to watch it religiously but work, and now my diet/workout routine just limit me on what I watch and have time for etc. But I still hear its a good show. May catch it on YouTube, which is what I've been doing with other shows that I like.
