Wondering If Hit Men Make Mistakes?

I don't know any hit men and don't want to know any.  But they are a fact of life, although a disgusting, cruel, dark side.  I do not know why anybody would stoop low enough to want someone killed and worse would be the hitman hired by these people to do their dirty work.  They have no personal interest in the victim except for the money they get to do the nasty crime.  The good ones are nameless and faceless:

I am wondering if they ever make mistakes.  Sure they do!!  Everyone makes mistakes and they are no different.  For example, a hitman was hired to do away with a Mary Morris.  He faithfully carried out his task, but then found out that there was another Mary Morris.  So, like any reputable hitman would do, he killed the other one, also, just to make sure that he got the right one.  Here is a picture of the two Mary Morrises.  The one on the left is Mary Lou and the one on the right is Mary McGinnis and both share the last name of Morris:

 

 

So, just because you have no enemies, don't feel too safe.  A stupid hitman may just make a mistake, they are only human, you know, although on the very bottom of  humanity's list.  Keep looking over your shoulder but I know you bloggers would not be on any hit list, so relax and have a great day, you hear?
