Hunger makes us yawn. That's why we decided to use our fan's webcams to reward them according to the size of their yawn. The bigger their yawn, the bigger their hamburger. At first we did it in our restaurants in order to make a video of the activity and spread the yawns all across the internet.

In the first weekend we had 3,570 winners , 31,000 persons visited our fanpage, resulting in 57% fans increase in Facebook. At the end 300,000 bigger hamburgers were given to our happy customers.
