A Derry, New Hampshire man was experiencing severe itchy, watery eyes and throat when he entered his basement. He only experienced these allergy-like symptoms on wash day when he entered the room to load up his washing machine and dryer. He thought this was rather odd and considered that the detergent could be the cause of his suffering because allergy season was far behind him. It was the middle of winter so the only thing that could be causing his reaction had to be the detergent or fabric softener, right? One day while he was loading up his dryer, he accidently tossed a wet sock behind the washing machine. He went to retrieve the damp sock from behind the washer when he caught a glimpse of a large dark patch on the wall behind it.
