I am unabashed in my affinity for the serial comma.
The caption reads: “The documentary was filmed over three years. Among those interviewed were his two ex-wives, Kris Kristofferson and Robert Duvall.†The case for the final serial comma, which would have made it abundantly clear that Kristofferson and Duvall were not, in fact, Haggard’s ex-wives, rests.
Thanks, Matt!
