One of the few differences between the Mr. Smith and Mr. Martin is that Martin manages to be even more forgetful than Smith. Smith may not be the brightest bulb, but at least he can remember what his wife looks like. It takes both Martins quite a while to remember each other. This hilarious and absurd process of elimination can perhaps be seen as a comment on the fallibility of memory. It could also be a comment on the subjective nature of reality. It forces us to ask, what would happen if the Martins didn't remember that they were married? Would that then mean they weren't? Much like with the Smiths, Mr. Martin's extremely shallow character manages to raise some deep questions.
