I had a different old cartoon picked out to show you and to discuss today, but I decided for once to finish something I’d started. Here are the final two episodes of “Rearranged Marriage,” completing the entire sequence that first appeared for one week in 2005. You might recall that not long ago I reprised this idea in a rather colorful Sunday. Did I deliberately sneak back and crib from the older comic strip? Not really. Not consciously. What usually happens in these situations is that I’ll get started on an idea and in creeps the nagging question: Have I drawn this one before? The answer in this case was, Yes.
