Lois: You listen to me, young man. That one lunch obviously meant a lot to Stevie. He's a human being with human feelings. Now, you are going to be friends with that crippled boy and you are going to like it. Understood?
Malcolm: Yes, ma'am. Understood. [to camera] If I give up now, I won't get the lecture.
Lois: You kids...
Malcolm: Dang.
Lois: You just take your legs for granted like nothing could ever happen to them. Well, let me tell you something, that is just wishful thinking. There's meningitis. There are car accidents. I could be giving you a spanking and accidentally snap your spinal cord. Every day is a lottery and first prize is that you don't have to scoot yourself around town on a skateboard with your hands. You think about that.
Dewey: I don't take my legs for granted, Mom.
Lois: I know, honey. You're a good boy. Stop playing with yourself.
