Let’s eat Mom!

which implies we are ready to eat Mom and make it more civilized with a mere comma.

The comma before the “and” in the second sentence is known as the serial or Oxford comma. In certain circles, debate can get quite spirited as to whether or not that comma is needed. In her book “Eats, Shoots and Leaves,” author Lynn Truss writes, “There are people who embrace the Oxford comma and people who don’t and I’ll just say this: never get between these people when drink has been taken.”

Why do some insist that the serial comma must be included for clarity, while others think it does nothing but clutter up text with unnecessary punctuation? How can such a little squiggle cause such an uproar?
