In celebration of the book launch (based on their Tumblr site) This is why you’re fat is running a one day contest that consists of the following: Six trucks tweeting their location every 20 minutes as the move around the city. Each truck has a TIWYF inspired menu item that day. Fans must hit each truck over the course of the day and reply @tiwyf with a pic of themselves eating the inspired item. The first person to reply tweet pics of them eating the inspired item at all six WINS! OK, if this doesn’t come to Nashville I’m starting my own. Who’s with me?!?!?!
