The restrooms in our office are in the middle of our building and they do not have any windows. My team made a pit stop on our way to a meeting; all three of us were standing up at a urinal using the restroom when a 50-year-old director turned out the lights and left. So the three of us were standing in a pitch black bathroom peeing. It was hilarious. We couldn't stop laughing at the third grade prank.
I asked one of my colleagues if he was scared to be in a dark room with a gay man, and he said no not at all, but he hoped we found the lights before someone else walked in the restroom because being found in a dark room with two other men would be an awkward thing to explain to his wife...this made us laugh more.
