Off-topic warning: This Squawk has absolutely nothing to do with baseball. Also, I will be talking about “Mad Men,” and “The Andy Griffith Show,” and important plot points of both TV series, so consider this a spoiler alert for both shows, and go read something else if you don’t want anything to be spoiled for you, or if you don’t care about the topic! (You would think I wouldn’t need to have to put “spoiler alert” about a program that debuted 50+ years ago, but I once got yelled at for talking about the ending of “Easy Rider” – 30 years after the movie was released!
