Karen and Lorraine sing along to "A House Is Not A Home" by Dionne Warwick.
Karen and Lyle get engaged.
Karen: So, what are you doing here, Lorraine? You've taken your father away from me and now you've come to rub it in my face?
Lorraine: I haven't come to rub anything in anyone's face, I already tipped the driver.
Karen: (about Lyle's reaction to Lorraine's misbehavior ) Oooh, Daddy gonna crack the whip!
Lorraine: (reacting to Karen and Lyle getting engaged) Oh, this is so exciting! Finally, the old man's getting married. And congratulations to you too, Dad.
Grace: I got a call on Zandra's place. Someone offered the most insane amount of money.
Will: How insane?
Grace: If the money were a person, it'd be Courtney Love.
Lorraine: (about herself and Karen) We're both money-grabbing, sex-starved women who are oft-timed mistaken for transvestites.
Will and Grace: (singing) Money, money, money, money... Money!
This is the chorus to the famous song "For the Love of Money" by O'Jays.
