For the fiftieth anniversary of Bobbejaanland themepark, the stairlift company Stannah gave away thousands of free tickets all people older then fifty. To create dome buzz ContentCowboys launched the Yoyoma & Yoyopa contest. The only thing people had to do was upload a cool picture of their grandma or grandpa (yoyoma & yoyopa!) and perhaps they could win a free entrance for the whole family too!
