Lois: Boy, this is weird. I keep thinking about why... things turn out the way they do. It's amazing how different your life could be if you just... changed one person.
Malcolm: Tell me about it. You know what else is strange?
Lois: What?
Malcolm: Have you heard a bird or a cricket or anything in the last two minutes?
Lois: No. Everything's gone as quiet as a graveyard.
[Lois and Malcolm scream as they turn around and see Ida standing at the door]
Ida: Judas!
