Quote from Chandler in The One with Phoebe's Birthday Dinner
Chandler: You're not allowed to smoke in this office though, right? Claudia: Yes. In Oklahoma, it's legal to smoke in offices with 15 people or less. Would you like one? Chandler: All right. I don't smoke any more. But if the rest of you want to light up, go ahead, it's fine. So you all smoke, then? You know, it's almost rude if I'm not smoking. Ken: That's not true. If you don't wanna smoke-- Chandler: Ken, please! Chandler: No, I can't smoke. If I smoke, my wife would kill me. Ken: I'm sorry. But isn't your wife back in New York? Chandler: I've always like you, Ken.
