Riddle: How quickly can you find out what is unusual about this paragraph? It looks so ordinary that you would think that there nothing wrong with it at all-and, in fact, nothing is. But it is a bit odd. Why? If you studyit and think about it, you may find out, but I am not going to assist you in any way. You must do it without any coaching. No doubt, if you work at it for long, it will dawn on you. What is it?
Answer: The letter "E" can not be found in this paragraph even though it is the most commonly used vowel in the english language.
