How Pitiful!

We're watching Celebrity Rehab on VH-1, with "celebs" such as Brigitte Nilson (or however you spell that), Jessica Sierra (from American Idol) and some others, but the saddest case is Jeff Conaway. He used to be so cute in Grease and Taxi, but he is just horrible and sad now. He has to use a cane or a wheelchair to get around and is totally incoherent. You can't understand what he's saying half the time. It just really makes me sad to see. He was such a talented actor and he wasted it all on substance abuse. I'm not even sure what substance he used, but whatever it was, it ruined him. I could just cry because I like him as an actor and he is going to die!
