Jimme Cayne may be one of the worst CEOs but the former CEO of Bear Stearns is a good bridge player.

After losing about $1 billion in net worth from the collapse of Bear Stearns' stock, he sold his entire stake in the company for $61 million.

In July 2007, the Bear Stearns' hedge funds collapsed, an indication of the impending global financial credit crisis.

In March 2008, as Bear Stearns was on the verge of bankruptcy, Cayne played bridge at a tournament in Detroit.
