David referring to Roseanne

I like how the trivia said he never referred to her as Roseanne. The only issue is funny is that the title of the series is Roseanne so that might make sense since he knows her first name but otherwise he could refer to her as your wife or Mrs Conner to Dan or your mom or your mother to her children, or he might say my girlfriend's mom to somebody who she doesn't know. Also, intersting is that Dan and Roseanne called their inlaws by their first names but David who is a different generation calls them Mr and Mrs Conner.Mark also called Roseanne Mrs Conner but usually he called Dan Dan since he worked for him. But I would think the younger kids would be less formal rather than the other way around.
