Lois: Hope everybody likes brownies.
Dorene: Oh, my, that is so thoughtful. Are those nuts?
Lois: Walnuts.
Dorene: Oh, gee. We can't have that. Some of the children are severely allergic to nuts.
Lois: Oh, my gosh, I had no idea. Whose child is allergic?
Dorene: Well, no one in this class specifically, but you can never be too careful. [empties tray into the trash] Believe me, this isn't meant to publicly humiliate you. I'm sure they were delicious.
