Doesn't Roger take Liz by the arm or shoulder and physically lead her out of the room to get rid of her? Maybe I'm thinking of another scene, but if not I think that's the funniest part of it all.
Could very well be, and sounds likely. I can see Roger closing the drawing room doors behind her. Poor Viki!
Another hillarious scene is when Charity/Pansey bumps Trask with her hip during one of her many performances of
I Want To Dance With you, in the foyer. That scene always makes me think of RobinV, and gets me howling with laughter!
And many of Roger's references to his son during the early eps, "The little monster", "Give him a kick for me", etc.
And in the interest of not going on endlessly, I'll make my last post in this topic with my all-time favorite moment in the show (which always cracks me up), when Liz turns to Roger in episode one and says, "Because I choose to do so!"
