Celebrity rehab? How did I miss this?

In scanning the channels this weekend, I stumbled onto the VH1 show Celebrity Rehab. I don't know why on Earth I haven't been watching this. I remember hearing that it was good it a trashy, train wreck kind of way, and boy is that true. No one seems to go off the deep end like famous people, probably because they're the only ones with the money to do drugs in really massive quantities. But it's a good time to hear their stories, plus there's the fun of watching Nick Nolte just be completely insane. (Edited to add: Kim was totally right, it's crazy Gary Busie, not Nick Nolte...I find them eerily similar...)
