That's a little bit of a shock that Jeff Conaway passed away. I know he'd be somewhat of an old man by now if he was alive, but he looked like one of the younger cast members of the shows. Did he abuse himself with substances or something? Andy Kaufman could be almost as funny as Christopher Lloyd's Ignetalski on the show once in a while. Of the characters, the ratty boss played by Danny DeVito was normal except that he was obnoxious at times. Tony Danza's character could be a little dense at times, which would mean the characters who were close to normal were Marilou Henner's character, Jeff Conaway's character, and Judd Hirsch's character. For the sake of making this as close to Star Trek as possible, maybe they could do a movie with the remaining cast members. I know I got a bit off topic here, but Star Trek itself has a tendency to do that at times in some of their books, and it even made it onto the screen with the two part Enterprise episode that took place in that mirror universe and didn't involve the main characters at all. I hate it when they do that.
