Quote from Lois in Long Drive
Lois: Aha! No coaster. Look at that ring. That is why I have to move out of this house. Malcolm: Mom. Lois: Every time you boys thoughtlessly mar the furniture by refusing to use coasters, what are you doing? Boys: Killing the baby. Lois: Killing the baby. Every time you run through the house, every time you destroy furniture, every time you fight with each other, you are killing the baby. Hal: Lois, the doctor just said you should avoid stress. Lois: Which is just medical jargon for the simple fact that every time you boys misbehave, you might as well be taking a knife and putting it in that baby's tiny little heart. Malcolm: Will you stop saying that? Lois: I just hope you boys have the character to channel the horrible guilt you should be feeling Into better behavior while I'm gone. Boys: We're sorry.
