Betty: Will you try being friendly just for me? Go over and give Fred the cup. Then ask him in a nice way to give you the dues he owes.
Barney: Well, I'll try it, but you know Fred. It won't work.
(Betty is later sitting in a chair reading)
Betty: I just know it will work. Fred's really sentimental. When he sees the cup, he'll soften up. And when Barney goes into that "Close friend, bosom buddy, lifelong pal," Fred will break down and cry. In fact, Barney will break down and cry, too, if I know him. Oh, they're a couple of sentimental guys. They really love each other. (hears the door open) Is that you, Barney?
(Barney enters with the cup over him)
Barney: I told you it wouldn't work.
