The highlight of this video depends on what kind of viewer you are. We’ve seen behind the scenes footage at MMA events and sat there mesmerized by the intensity exhibited following an epic battle in the cage. We’ve also seen all sorts of bromance and tomfoolery, but we’ve never seen Dana and his buddies prank Lorenzo Fertitta. Although he didn’t react dramatically, we’re hoping that this harmless prank is the beginning of something special, and by that, we mean billionaire prank wars. If you find yourself mildly entertained by what happens when fighters prank one another, just imagine what they could do if their bank accounts knew no limits. In fact, you have a duty as a MMA fan to tweet Lorenzo Fertitta and insist that he return the favor and make this a prank war of ambitious proportions. If you aren’t part of the solution, you’re part of the problem – and if pranks aren’t your thing, well, then just enjoy the behind the scenes footage of UFC 155 in day two of Dana’s Vlog.
