Yup it's pretty cool - for the holidays we have the Maintain, Don't Gain program - where you weigh in just after thanksgiving and then again just after New Year's - if you're within +5lbs or lower of your starting weight you get some kind of decoration hanging in the gym. (The Turkey Melt has turkeys for the various participants on the windows - one for 1k cals burned, 2k etc).
With how thin you are sparrow, I'd think your having 4k calories in one sitting would have you looking like you were pregnant or something lol
