David, Joanna and Christopher dive into the hidden world you didn't know was lurking behind the reviews you see on Amazon. Then reporter Deepa Seetharaman comes in to explain the latest in a long line of Facebook scandals, and debate what might happen next. Since it's that time of year, the three hosts offer last-minute gift ideas, then David interviews director Gary Hustwit about his new film "Rams." They talk about the film's subject, the famed designer Dieter Rams-and why he says if he could start over, he wouldn't be a designer again.
