Panel 1: It's Christmas morning at the Patterson house; as Mike and Lizzie's eyes light up, Elly watches the joy on the faces of the children looking at all of the presents and tells John that they almost can't believe their eyes.
Panel 2: She wonders what precious thoughts are running through their little minds.
Panel 3: It turns out that the 'precious' thoughts are what we call 'bug-eyed greed' and 'the overweening desire to delight in the suffering of a hated enemy.' This is because both Michael and Elizabeth wish all the presents were for them.
Summary: I wonder what Katie and Aaron did to piss Lynn off this time. I also wonder if this is a general comment about how suddenly, children are heartless and materialistic.
