Lets see,

With 33 years at his joint he accumulated a 58 billion net. worth that makes his net annual salary:
58,000,000,000/33 = 1,757,575,757 US$
Between 5 and 7 there’s 6 ofcourse…
6 can be put in above result 6 times
1,76567,56765,76567
=> 666 666

So yes, he is Satan, twice even (2 x 6 months) for each year for the past 33 years ;o)

Nice one Bill!
