In “It’s All in the Game,” Faye Dunaway is a very wealthy woman (who throws awful-looking parties) plotting with Claudia Christian to murder the gambling Lothario who’s been two-timing them both. When Lt. Columbo is assigned to the case, Dunaway tries to distract him with gifts, smooching and cocktail dates. Wait, what? Columbo, unfaithful to Mrs. Columbo? Say it ain’t so! Well, turns out it ain’t. Who’s playing the game in the title? You might be surprised. A very patient Carolita Johnson (The New Yorker, carolita.org) returns to the show to listen to Jon and RJ jabber incessantly about Cheers robots, kink shaming, John Finnegan, lesbian signifiers and oh, so much more.
