Re: What happened with Kes and Neelix?
Roddenberry smoked, as did Shatner and others. I think there's an early memo where Roddenberry decided the Enterprise would be no smoking to make it seem in the future.
Moe: I'll take the blonde!
Larry: I'll take the brunette!
Curly: I'll take the Black and Tan!
