Panel 1: We start things off with Mike grabbing a box of chocolate chip cookies out of the cupboard.
Panel 2: Since he's a means by which Lynn can be a passive-aggressive jerk about Aaron's appetite, he grabs a big handful of cookies.
Panel 3: He then goes to the fridge with cookie box in hand and drinks milk right out of the carton like a thoughtless slob.
Panel 4: As he watches television, he starts to methodically gobble down a bowl of fruit.
Panel 5: Since he's a growing boy, he's still hungry so he raids the fridge yet again.
Panel 6: The result of his search is a chicken leg.that he's gobbling down without re-heating it. He should thus prepare for a visit from his friends Sam and Ella.
Panel 7: Next, we find him sucking on a juice box and eating a big bag of taco chips.
Panel 8: He goes back to the fridge because he's still hungry.
Panel 9: Having noticed something not to his liking, he yells "Hey, MOMMMMMM!!" in order to get Elly's attention.
Panel 10: We see what Mike's problem is when he asks her why there's never anything to eat around here: he's an idiot who doesn't understand cause and effect.
Summary: The "punchline", such as it is, hints broadly as to what any comments might be: Lynn complaining about sons who she can't fill up who don't understand that a fridge isn't a food replicator from Star Trek. Someone has to buy the grub and duds and it ain't him.
