Merry AFTER Christmas!
All of the gifts are unwrapped, there's a huge pile of garbage sitting on the sidewalk, and you're so tired from shopping and dealing with your immediate family that you feel you need another holiday just to recover!
This year instead of celebrating Christmas itself, why not celebrate the fact that it's finally over? Mission accomplished! Get ready to have a Happy New Year!
... as a side note. After I replaced the chainsaw with "kitten mittens", this drawing kind of stopped making sense.
