Diane: Well, even if I can't do both, I don't care.
Sumner: Of course you don't. Sam's bludgeoned all the spirit out of you and dragged you back down to his level.
Diane: No one was dragged, Sumner. Sam and I walked arm in arm to his level. I think you'd better leave now.
Sumner: Yes, I'll leave. But the time will come when you'll look back on this moment and realize you've made a terrible mistake. I'm glad I won't be around to witness that.
Diane: So am l.
Sumner: Touche. How appropriate that as I take my leave of you, you are holding the eight ball. Good-bye, Diane.
[As Diane throws the eight ball into the pocket and walks out of the back room, Sam emerges from under the pool table with a screwdriver in his hand and the eight ball wedged in his mouth.]
