一段有趣的文字

百科就是百科。刚刚在维基百科上看到一段有趣的文字，至于它为什么有趣，各位自己看吧^_^

This is an unusual paragraph. I'm curious 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!
