Why (oh, ye gods of Olympus, why?) am I doing it again? Because it’s a very famous (and famously active, in its day) penis. And, more simply, because it’s there. Specifically, it’s there at urod.ru — scroll down at your own peril, you’ll find an absolutely huge closeup of the jar and detached (pickled) manhood, in living (dead?) color.
I’m about to link to a much-reduced — but still very graphic — copy of the photo, as a hedge against future link rot. Don’t blame me if you decide to look.
It’s grisly. Seriously.
