Malcolm: Bye, Mom. Say hi to Francis.
Lois: Oh, wait, wait, all right. You've got your food money. You've got your emergency numbers. We'll be home Sunday night around 9:00. But before I forget. [picks up vase] This is the one thing left in this house that I care about. I don't want to spend the next two days worrying about "How will they break it, where will they hide the pieces, how will they lie to me about it when I come home." So... [drops vase on floor] There. Now I can relax.
