On the Sixteenth Day of December...

I've been walking to work without a hat so far this winter. This was fine when the it was in the 50s like yesterday, but when it dropps into single digits like today (high of only 12 degrees!), maybe I should keep my head, or my ears at the very least, covered. Now how do I combat the inevitable hat hair when I get to work?...
