GIANT GALACTIC SPACE DICK
All right, my information about this is sketchy to say the least. I was directed to a website in Russian where pictures of this, quite frankly, amazing practical joke were stored. Since I read very little Russian and every online translator butchered the words, I'm having to fill in a few blanks. If I get this wrong, it's not intentional.
On June 14, 2010, Pranksters from the Russian art-group Voina, Russia wowed the entire city when a St. Petersburg drawbridge (called the Foundry Bridge) stood erect and a massive penis stood tall and proud for the entire city to see. This massive member was apparently painted by using paint in milk jugs and was created in 23 seconds by 40 collaborators while the bridge was flaccid. One was arrested while painting the left testicle.
