Mary over at the Cameron Village Chick-fil-A reminded me the other day that Friday is Cow Appreciation Day at all Chick-fil-A restaurants.
This is the day when customers dressed as cows receive free food. If you arrive partially dressed as a cow (like with just a hat or scarf), you get a free entree. If you're dressed as a cow from head to toe, you get a free meal.
Check Chick-fil-A's website for all of the official rules and details and a "cow starter kit."
