there is nothing unrealistic about the setup in the programme. it is by no means a stretch of the imagination. it's not like the programme is about dwarves and elves which is far more unrealistic

Yes but we're not talking about reality! We're talking about characters that have been
created
. I just find it unusual that the writers would have given them the same name!

smith is the most common anglo name in the world. so most unlikely

It is an inconsistency, but Smith is the most common last name in the United States, they very much could have both been Smiths, therefore, a last name wouldn't need to change after marriage.

Wait now there are dramatic inconsistencies and then blatant ones. The series was far enough along at that point to make such a mistake.

I think the last name thing was an inconsistency, lots of sitcoms have them especially when it's an episode from the first season and a much later season episode. Kinda like how on Friends how they kept screwing up their ages throughout the series.

Maybe they were second cousins who got married? That would explain A LOT.
