If this doesn't show you my devotion to all things Christmas, I don't know what will.
One year, for work, I was Santa Claus for Halloween. My coworker was an elf. Last year, I was a Christmas present (easily done since Christmas stuff comes out in the stores in September/October) I bought a round Christmas table cloth, cut a hole in the center to pop my head through. I bought a card, put it in an envelope, taped it to the front of the table cloth - wrote To: Mike From: Santa....and topped it off with a bow on my head.
