Riddle

[Primo Carnera]

This is a most unusual paragraph. I'm curious as to 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. But if you work at it a bit, you might find out. Try to do so without any coaching or Googling

Sorry, I couldn't resist googling it. Very clever and very interesting.

Your post is not unusual, my post is.

WTF is going on?

Your post in actually unusual

But this post is also unusual, don't you think?
