The Bill Gates fans used to like to sell that story too:
Harvard drop-out nobody starts company, sells software to IBM, becomes mega-billionaire.
Over time it became better known that his grandfather was a bank president, his father was a rich lawyer, his mother was a banker and sat on several boards of directors, and that he got the initial contact at IBM because his mother sat on the United Way board of directors with IBM's CEO John Opel and bugged him about it.
