Quote from Diane in Diane Meets Mom
Hester Crane: Listen and listen carefully. Stop seeing my son or, as God is my witness, I'll kill you. Frasier: [returns to the table] Something to munch on. [leaves] Hester Crane: Yum, yum, yum. [to Diane] Now listen to me. I have a gun, I know how to use it. Frasier: Here we are. Hester Crane: Oh, doesn't that look lovely? What do you call it? Frasier: Well, it's a delightful pear liqueur. Hester Crane: Oh, sounds delicious, doesn't it, Diane? Diane: Uh... Uh... Hester Crane: I think she likes it.
