Hmmmm.....Maybe Lynn has gone into straight reprints.
Panel 1: As Elly peels carrots in the background, John angrily states that if he has to eat more rabbit food, he'll leave home. Only in his diseased mind is having to eat a vegetable (to use the proper word for what disgusts him so) considered grounds for divorce.
Panel 2: He does get a little more grounded in reality by pointing out that it's crazy to diet now because they'll just gain it back over Christmas.
Panel 3: We next see a rather confusing panel as his waistline expands. The confusing part is that it takes milliseconds and is accompanied by the word BULGE floating in mid-air next to his belt-buckle.
Panel 4: He then testily asks her to pass the lettuce.
Summary: It isn't just Elly's insanity that causes his children to grow up with an unhealthy disrespect for good food. John's dismissive attitude towards anything that isn't high-caloric slop helps his kids eat like idiots.
