Continuity mistake: When Jack is stuck for a special guest on his show Jack-Talk, he surprisingly introduces Grace to be his guest. As she turns around on the sofa and sits down, there is a yellow and brown cushion on the sofa sitting to her right. But in the next close shot of her, it is under her arms as she leans on it. In the next shot the cushion is to her right, sitting on the sofa again. Then as the scene continues, the position of all the cushions on the sofa surrounding Grace keeps on changing!
