To mark Episode 400, we’re talking about good riddance to James Corden, Don Lemon, and Tucker Carlson; Katy Perry & Take That to sing for the new king; hell froze over because Charlie Sheen & Chuck Lorre are working together again; Netflix rolling out paid password sharing; the Oakland A’s are officially coming to Vegas; the Champagne of Beers gets dumped; sell the dog to return to the office?; cruisers get banned for fishing off their balcony; and, much more pop culture silliness of the week.
