The chicken sandwich chain that uses a cow character to encourage people to "eat more chicken" has a challenge for their loyal customers.

Chick-fil-A will give out free sandwiches and other entrées to customers who dress like cows on July 11.

The rules? Wear anything that resembles a cow and you get the reward.

Here are some photos from previous years for inspiration:

You could wear a full cow onesie

The event will go from opening time until 7 p.m. on July 11.

As we saw Thursday morning outside Raising Cane's Chicken Fingers in Highlands Ranch, people will do a lot for free chicken.
