The real name of Bill Gates is William Henry Gates III. Nowadays he is known as Bill Gates (III), where ``III'' means the order of third (obviously).
By converting the letters of his current name to the ASCII-values and adding his III or adding 3, you get the following:
B I L L G A T E S (III)
66+73+76+76+71+65+84+69+83+3 = 666
Some might ask, "How did Bill Gates get so powerful?" Coincidence? Orjust the beginning of mankind's ultimate and total enslavement? You decide!
(The numbers are obtained by translating each character (letter, number, space, etc.) into its corresponding ASCII value.) It looks like well-known OS's fall into the same category:
M S - D O S 6 . 2 1
77+83+45+68+79+83+32+54+46+50+49 = 666
W I N D O W S 9 5
87+73+78+68+79+87+83+57+53+1 = 666
