In American movies, I'll sometimes you'll hear "Mr. and Mrs. John Smith" when introducing a couple at an extremely formal event where everyone wears tuxedos and such. I've never been to such an event before, so I don't know how accurate that is. But it's definitely something odd I've noticed in movies.
My first wife was an M.D. (and did not change her last name), and we occasionally received wedding invitations addressed to “Mr. and Dr. Aaron Harnly”, which I found hilarious. The endurance of the patriarchy and its subversion, all in one line.
