At the over 1200 Chick-a-Fil restaurants on July 9th there is going to be some crazy stuff going down. Anyone who shows up fully-dressed like a cow will get a free meal. Notice the fully-dressed clause - so if you go be sure and be fully covered in cow costume. That appears to be the only rule for this so creativity is wide open.
Team FPT is wondering why a cow and not "dress like a chicken day"?
