Sometimes a riddle is very easy, but its very tough to make other understand what is your answers. This is the case especially when other party is not in the mood to understand :). The question could be as easy as What is the First Alphabet in English Language. Do you know that answer? Looks Easy!! However can you make the other person understand your answer? If your answer is yes, look at this video where this question is put in "Who wants to be a Millionaire" as Million Dollar Question and contestant failed to answer it correctly. I hope in this video the host has done his Insurance cover as he has done as considerable damage to contestant of this game :). Watch it out and post your comments about it.
Do share it with your friends and see if they can answer this easy brain teaser :)
