A man joined a big multi national company as a trainee. On his first day, he dialled the kitchen and shouted into the phone "get me a cup of coffee quickly!". The voice from the other side responded, "you fool; you've dialled the wrong extension! Do you know who you are talking to?" "No" replied the trainee "it's the managing director of the company you idiot". The trainee shouted back, "and do you know who you are talking to you idiot?" "No" replied the managing director "Thank God!" replied the trainee and put down the phone.
