Scout Creative releases a free printable calendar you can assemble into a 3D paper toy. These always make me smile, and May's edition is one of my faves. Build yourself a coffee cup with a calendar sleeve. When the month is over, remove the sleeve to reveal a feisty face on one side of the cup and a happy face on the other. (You could rotate it daily to warn your coworkers about your emotional state.) Grab the PDF right here.
