Kaitlin Olson and Rob McElhenney spoke with 'Variety' for a recent cover story, opening up about everything from their almost 17-year partnership to parenting their two boys. Olson revealed that she's still mad at McElhenney for doing one thing that they agreed they wouldn't do: show their children's faces in public.
