Not a strong case to prove any sense of objective truth. But in that same sentence there's only so much to disprove. Although there are some factors to consider, one being the simple statistical data that goes against the idea of a giant giant cock like that, which just doesn't happen if the data is to be believed. And secondly the patron steps away from the camer, which isn't wrong so much as there is a reason he stepped away and it could be so we don't get a clear image of what's going on. Also its still a grainy image to begin with and furthermore we only see him do so much and its not enough to say anything conclusive.
Again no real data to say yes or no, but my instinct says no just because its so abnormal, and I don't like that he steps away from the camera and doesn't do anything.
