Violet and Roscoe...

I think both of these kids make for really lousy characters. They don't bring much of anything to the show except annoyance and unnecessary drama. Violet is just a little bitch whose drama doesn't seem to have any of the comedic element needed for a show like this. And Roscoe is like an irritating little gnat you can't seem to swat away, and is just as easily forgotten once he's off screen. Christy and Bonnie are the perfect odd couple and bring enough laughs to the show without the "benefit" of the kids.
