Can you find out?

This is an unusual paragraph. I'm curious to know how quickly you can find out
what is so unusual about it. It looks so plain you would think nothing was
wrong with it. In fact, nothing is wrong with it! It is unusual though.
Study it, and think about it, but you still may not find anything odd about it. But
if you work at it a bit, you might find out what is wrong. Try to do so without any
help.


PS :Give it a shot, and I will give you the answer if you give up
