(Strip Number 1319, Original Publication Date, 23 July 1988)
Panel 1: It's John's turn to try (and fail) to convince Mike that he isn't being punished for being young and having free time by being sent to camp (when everyone who ain't Lizzie knows he is) by saying that he's only going to be there for two weeks (it actually swallows up most of August) and anyway, Kamp Kawkawa will be a vacation.
Panel 2: Mike doesn't think it's a vacation at all and explains why when he reads from the camp rulebook. What sort of vacation, he asks, requires him to make their own beds, do mess hall chores, be ready for activities and obey camp rules at all times. The implication of this is that he might as well be at home because he has to do endless chores without reward or recognition so he isn't really getting a proper vacation at all.
Panel 3: John's smug and ultra-predictable to everyone who AIN'T Michael (who looks honestly shocked despite the fact that he really should have known better) of "OURS!!" reminds us that he and Elly not only don't really like having him around, they also don't like the idea of his having time to just kick around by himself.
Summary: What they actually like is to dump him on other people who also insist on a million fussy little rules to clog his days and waste his life because they fear and hate the idea of his just sitting around doing nothing in particular. Super idea, Trash Bag Johnny. Get other people to teach him the discipline you and your idiot wife are too fucking dumb, lazy and angry to.
