Monica: It's actually going to be just family.
Janice: Oh, wait. You two think of me as family? Oh, I have to ask you something now, and be honest. Do you want me to sing "Careless Whisper" or "Lady in Red"?

Monica: Oh, my God! Oh, my God! You have to go.
Janice: Why?
Monica: Because Chandler still has feelings for you.
Janice: He does?
Chandler: Say again?
Monica: That's right. That's right. And that is why you can't stay here tonight. And probably why you shouldn't come to the wedding.
Chandler: Feelings. Such strong feelings.
Monica: I mean, I realize that his feelings may never completely go away, but you can.
Janice: Oh, my God. I understand. I am so sorry. I'll go. Goodbye, Monica. I wish you a lifetime of happiness with him. Chandler, you call me when this goes in the pooper.

Monica: Come on. So she comes to the wedding. Maybe it won't be so bad.
Chandler: You think she's just going to sit there quietly? You don't think she's going to want to make a toast? You don't think she's going to want to grab the microphone and sing "Part-Time Lover"?
