There's a Facebook offer where you just have to watch a trailer for a new TV show and you'll be able to print out a buy one/get one free Chipotle coupon.
Not sure how to share it with you, but I searched for Chipotle on Facebook and saw they had posted this link on their fan page, so you could try that:

FYI: The coupon is good through March 3. So if you're on the February bring-your-lunch challenge, that gives you a couple days in March to take advantage without breaking your February commitment!
