Unusual Riddle

This is an unusual paragraph.I am curious as to just how quickly you can find out what is unusual about this paragraph. It looks so ordinary and plain that you would think nothing was wrong with it.In fact,nothing is wrong with it!But it is highly unusual though.Study it and think about it but you still may not find anything odd.But if you work hard,you might.Try to do so.
