What on Earth does this prove? He's measuring with his penis pointed almost parallel to his torso. He's also measuring with a tape along the curve which adds length.
Here's a much more indicative photo of him measuring:

Although this photo is better, it's still not technically 100% correct. Measuring needs to be done with a ruler since length is a one-dimensional measurement. Measuring with a tape will yield an inaccurate result because of his downward curved penis. You wouldn't measure an upward curved penis along the underside, right? So same idea with a downward curve. Has to be a ruler. You can try to straighten out the penis while measuring, but using a tape is very inaccurate.
Even still, with the advantage of a tape along his downward curve, it looks like he comes out to somewhere between 9 1/2 - 9 3/4" bone-pressed. With a ruler, it would undoubtedly be a tad less.
This is nothing against Quercusone, as he has without question one of the longest verified penises out there, but it's just stupid to be linking photos of him measuring in crazy, inaccurate ways. It's huge and bigger than almost anyone. but it still is shy of double digits if measured with complete accuracy. Just like every other cock documented on here.
