Working in a sewer has to be one of the toughest jobs around. This is a place filled with stuff that gets flushed down the toilet or whatever drains in off the street. Any kind of work that requires people to be around this cannot be much fun. One might also think that the brave men and women in this field have a pretty straight forward job to do with little excitement. Although, every once in a while they do rescue animals and people. On other occasions, these city workers come across some very interesting finds that defy explanation. Take a look at the top 22 things found in sewers. #4 really freaked me out.
