Working in the Work-a-Day World

I was asked to compose the holiday greeting card for the large company I don't even work for. This is what I came up with:

"If you live north of the equator, it's cold this time of year!"

I thought about adding something along the lines of "This is a really stupid assignment," but I said fuck it and left it as is. I did a pretty fair to middling job, don't you think? In the end I didn't want to grandstand or make the full-time internal copywriter feel threatened or make her think her job was in jeopardy.
