A young man wants to marry Bill Gates’s daughter. He goes to Bill Gates and asks for his daughter’s hand in marriage. The billionaire suspiciously asks the young man, “Who are you? I will only marry my daughter to the CEO of The Bank of America.” “No problem,” says the young man and leaves. He goes to the Bank of America, applying for the CEO position. When he gets interviewed, the interviewers ask who he is. “I’m the future son-in-law of Bill Gates,” he replies.
