Extremely high roller

Its like those million dollar insurance policies on a movie star's legs... its the publicity about the policy that makes money.

You can watch a youtube clip about a man who bet his life's savings of about 132,000 on one spin of a roulette wheel (he won). Binions years ago let someone but 240,000 on the line at a craps table (player won, came back a few years later and lost...blew his brains out in his room later).

Usually people smart enough to have a million dollars don't bet it on zero anyway.
