Martin: Well, maybe you and Niles can cheer each other up.
Niles: [nervous] Dad...
Roz: Why, what's his problem?
Martin: Oh, Daphne's got a new boyfriend and it's eating him up.
Niles: Dad!
Roz: What? [to Niles] You've got a thing for Daphne?
Martin: What, you didn't know that after all these years?
Roz: No! I can't believe Daphne never told me.
Martin: Well, how could she? She doesn't know either.
Roz: You're kidding!
Niles: Yes, yes, he's a great kidder. Now, you Dad, run along, and you be very careful crossing streets!
Martin: [to Roz] Six years, can you believe it? Some people just don't even know when it's time to pull the plug.
Niles: Well, I won't make that mistake twice.
