The principal called all the students into the gym for a meeting, every 4 years a student is selected to be Class Cow. The Class Cow has to wear a CowChoker with a CowBell and a CowOnesie (or a CowBikini) so everyone knows to give them free food, belly rubs, etc. The ClassCow has to get to the minimum weight of 350lbs before they graduate, if not then he or she doesn't pass the school year. You are a female freshman, at 170lbs, getting bigger would have a greater risk of being chosen.
