Explanation: This joke plays on the titles of two popular shows: “Doctor Strange” and “Stranger Things.” The punchline humorously suggests that the speaker prefers to watch “Stranger Things” instead, implying that he has something more interesting or entertaining lined up, while also using wordplay between “strange” and “stranger.” The twist is in the unexpected prioritization of a different show based solely on its name.
