We brought you a fan earlier this summer that showed solid support of the Denver Broncos with a massive back tattoo. That's nothing when it comes to Dallas Cowboys superfan "Tattoo Mark."
As you can see in the video above, Mark Shenefield has tattoos of Roger Staubach, old Texas stadium, Tony Dorsett, Tom Landry, five championship trophies, Emmitt Smith, Troy Aikman and Larry Allen.
You'd think that would be enough, right? Nope, Shenefield plans to get more on his head and legs.
