Panel 1: We find the Pattersons at a burger stand (complete with a mutant cook and an army of cluster flies swarming everywhere) eating lunch on the drive home; John, who refers to his meal as 'real roadside rotgut', and Elly, who agrees with the assessment, are eating hamburgers, Lizzie is about to choke to death on a hot dog and Mike's floating, disembodied head is about to eat whatever floating, disembodied heads eat. As spittle flies from Pattermouths, Elly mutters MMMMM in appreciation. As expected, she's got her mouth full.
Panel 2: Elly stares testily at a disgusted John who asks her "Don't tell me you're enjoying this stuff!" Mike has probably gone off to the can to retch after seeing how Lizzie has ripped her bun to shreds and dropped its pieces from an elevated left hand and totally ignored the hotdog. That, or he's about to summon assistance because she's choking to death because she's not old enough to eat solid food.
Panel 3: As Liz has become just a pair of hands tossing the hotdog she's too young to eat into the air and a green-faced Mike is probably either being asked by off-camera passers-by if she's okay or administering the Heimlich maneuver on a toddler, Elly tells a gob-smacked John that it's amazing what tastes good when you don't cook it yourself.
Summary: This look at unhealthy, slobby eating and juvenile thinking is the direct antecedent of the infamous "It's not junk food if you cook it yourself" thing from two years ago.
