Thanksgiving is going to be quite the ordeal on The Real O'Neals.

As the family adjusts to their first turkey day since Eileen (Martha Plimpton) and Pat (Jay R. Ferguson) split up, there will be a few new guests at their home celebrating the holiday—including VP Murray (Matt Oberg), and his mother, Victoria Pauline Murray (Susan Sullivan).
