Joe originally told me this story a few years ago. Read on the link above as well as Packer (the richest man in Australia) was quite a man.
Packer is famously quoted for an exchange in a poker tournament at the Stratosphere Casino, where a Texan oil investor was attempting to engage him in a game of poker. Upon the Texan saying “I’m worth $60,000,000!” Packer apparently pulled out a coin and asked nonchalantly, “heads or tails?”, according to Bob Stupak’s biography. Some variations of the story put the sum at $100,000,000 and claim the line was “I’ll flip ya for it”, but Bob Stupak claims to have witnessed it.
