I was wrong; it's a mildly edited version of Mike being defiant.
Panel 1: We start off with Mike and Lawrence watching Lynn's take on Veggie Tales on a television set that has dials. Lawrence reminds him that Elly said that they have to go outside. He should remind him that in the original version, he was watching something else.
Panel 2: He doesn't do that but he does say "She said to turn off the T.V.(sic) right now. So how come you're still watchin' this stuff?"
Panel 3: Mike's answer: "She's not mad yet."
Summary: This "means" that Mike doesn't respect Elly or listen to her. This also means that Lynn clearly hates small children; why else would she depict them as being such utter little shits all the time? A normal mortal would realize that Mike wants attention and is willing to do anything to get it. Not Lynn; she wants her children to sit in the corner like little grinning idiots and not bother Mommy with their unfair need to take attention away from her.
