A Case for the Serial Comma
The serial comma is the final comma before a conjunction (and, or, . . .) in a series. Its omission can result in confusion at worst or humor at best. That’s why most style guides prefer it. Here is an example of a humorous need for it (after the name Kristofferson).
The quote under the photo, in case you can’t read it, is this:
MERLE HAGGARD: The documentary was filmed over three years. Among those interviewed were his two ex-wives, Kris Kristofferson and Robert Duvall.
A comment on the caption, attributed to my copyediting colleague Bob Allen, in eastern Washington:
With those two ex-wives, I understand why Merle looks so Haggard.
