Meh, I've seen bigger.
At my university, back when I attended it, we had these kiosks which were about 15 feet tall and cylindrical in shape. A prank played by someone had placed a paper-mache phallus over one of them, extending it to 25 feet in height.
The phallus was quickly removed. Nobody knows who did it to this day though.
My masculinity is by no means threatened.
