If you were to tell Matt Stonie that something is impossible, he'd just laugh in your face and devour that something. Today, he's taking on the "Impossible Big Mac Challenge." Four Big Macs, four large fires, and four large milk shakes. The kicker is he had to eat it all in under six minutes. Of course, he's Matt Stonie, so that food is gone faster than the McRibb when you've got a craving.
