I hate being right.
Panel 1: We start off with Mike whining that he doesn't want to eat this, Daddy. John says that they're beans, he likes beans.
Panel 2: Mike pouts that Elly makes them with wieners. John counters that, for some mysterious reason, they don't have wieners. Little does he know that the wieners are all in those indigestible casseroles that are all still in the freezer.
Panel 3: Mike then asks if he hasta eat ALL of them? John, who is obviously meant to be pure evil, says that if he can't or won't eat all of them, Mike should at least eat half of them.
Panel 4: As we see Mike rearrange his beans into two piles, John asks what he's doing.
Panel 5: Mike says that he's counting.
Summary: Lynn's intent is clear; she means to show us that John cannot handle a picky eater; it's too bad that she's making Mike act out of character. As a Patterson, he doesn't care what's in front of him as long as he can muscle it down his throat.
ETA: Today's seasonal banner wishes us a magically delicious St Patrick's day.
