Ahhhhh, you mean the furry wall. It was a fungus covered wall which was repackaged as a urinal. If you needed to do a number two, well, pardon the pun, but it was tough sh!t. There was no roof, no sink, no toilet bowl, no privacy, no toilet roll; it was just a wall. The only advantage was that you could keep watching the game while you took a leak.
Take a pity on any lady who needed to answer nature's call as there wasn't even a hole in the ground.
