Not quite CIDU as to overall idea, but invites explications or disputations of how each one works or doesn’t, or how some other plausible candidates could have come out.
From Le Vieux Lapin, this is probably not an overall-CIDU: notice the classic joke structure, with setup in panel 3 (along with 5) and the payoff in the final one. But along the way there are several bits which can stand in need of explication, for different readers.
For instance, I have never run into pay-as-you-go gas meters in real life (for tenants to get heat or hot water), but sort of know about them from vintage British movies and some novels. (Though it says a quarter and not a shilling so this may be American.) Maybe somebody understands them better — is electricity paid for this way anywhere? And the Patreon structure of “levels” — is this known widely outside of Patreon users? And does the girl’s litany of questions come from anywhere else in this wording?
