Lois: All right, Dewey, I know what's going on. [starts looking around her room] I know it's you. If it were Reese, he'd be bragging to everyone about it. Malcolm doesn't have the patience. So, that leaves you, Dewey. If I had any proof, we'd be having this conversation while I was walling you up inside your bedroom closet. [sighs] This is about the volcano, isn't it? All right, I acknowledge that perhaps I was a little inconsiderate of your needs, but that in no way justifies these petty attacks. Still, we have to move on. So, here's the deal: In the future, I promise to be more attentive and aware of your feelings, not that being the loving mother I am, I wouldn't be doing that anyway. Ah-ha! [sighs] And in return, you will promise to stop this stupid campaign to drive me crazy. Just give me a little sign that we understand each other. [two taps] Good.
