It was a really hot day at the office. The air conditioning was out and there were about 20 people in close quarters and everyone was sweating, even with a fan on.
All of a sudden, people started to wrinkle their noses at an odor passing through the air. It was the most hideous smell anyone had ever smelt. One man said, "Uh oh, someone's deodorant isn't working."
A man in the corner replied, "It can't be me. I'm not wearing any."
