It’s a well-documented fact that Alex Trebek can talk at length about almost anything. Things were no different when the longtime “Jeopardy!” host spoke with Vulture writer David Marchese for a piece that appeared to be about the 78-year-old’s much discussed retirement plans. But in reality, it was, at times, a bizarre interview that went far beyond a discussion of his experience as the beloved host of one of television’s longest-running trivia game shows. The Q&A, which Vulture noted had been edited and condensed from two conversations, was published Monday on a number of topics.
