I hate to be "that guy" and you can neg me all you want, but this looks to me to be photo shopped. In fact, if you look closely enough you can see a five floating near the middle guys left thigh, which I take to be the chest of the actual runner.
the guy on the right is like "SHIT" and the guy on the left looks like he is trying to look like he had on part in that at all
the guy on the left is like "don't look whatever i do i won't look.
It look's like that the guy in the middle is trying to fart in that guy's face!
