If you've been graced to see it, you'll "get" this post. If you haven't... go watch it, NOW (not the Kiera Waif-ly version, but the REAL one)!
Since it's Friday, there are two freebies for you. One of them requires you to put forth some effort, and the other doesn't.
On Halloween only, you can get a free Black Jack Taco after dark at Taco Bell (no effort, just show up after dark).
Also on Halloween, between the hours of 6pm and close, you can get a free Boo-rito at Chipotle. But it requires you to dress up like a burrito (or a bowl, or a taco).
