Disobey Gravity

I was watching a vid today of Sharma working a bouldering problem that apparently had never been sent and when he finally did it, he said something along the lines of "if I was to rate that, I would give it a V15 but I am not going to rate it." I both laughed in amusement at his "it really doesn't matter what it's rated cause it was H-A-R-D! attitude" and boggled at the idea of V15.
