In an ingenious, holiday-themed effort designed to call attention to the importance of the Oxford comma in certain situations, San Francisco-based MUH-TAY-ZIK | HOF-FER has launched a browser bookmark-let that will automagically add missing Oxford commas.
A video accompanies the effort with clear examples as to why you really should employ the Oxford comma at times. The video says "Missing Oxford commas ruins Christmas." It then cites some unintended results such as "I was shopping for your Christmas presents, toilet paper and prunes," "We went caroling with our dogs, grandma and grandpa" and "Merry Christmas from your parents, Santa and Rudolph." Images accompany the statements to illustrate just how wrong those sentences are without the Oxford comma.So if you're ever confused as to whether or not the Oxford comma is necessary, you can recall the awkward examples given in the video.
