Kitty: Okay, Red, remember, don't tire yourself out today, because tonight is a special night in the bedroom.
Red: Bob Newhart's on Carson?
Kitty: No, silly. It's been a month since your heart attack. Tonight's the night the doctor gave us the "okay." You know, the "okay."
Red: Kitty, I don't like clues, just say it.
Kitty: The okay to make love.
Red: Don't say that. [Eric enters]
Kitty: Well, tonight is my only night off this week.
Red: Let's not talk about it in front of the boy. Or girl, or whatever he is today.
