It took Youtuber Matt Stonie three attempts but he's not only started a challenge but set the record for the fastest time to eat a Grand Mac meal from McDonald's. Now to provide a little context, the Grand Mac is over twice the size of the original Big Mac and is a only available for a limited time. In addition to taking down the burger Matt also ate the large fries and diet coke (formerly known as SUPER SIZED) all under one minute. You have to see this!
