Virgin Group CEO Richard Branson on Dec. 10 bet Willie Walsh, chief executive
of British Airways owner International Consolidated Airlines Group (IAG), that
Virgin would still be in business in five years. In lieu of the £1 million
($1.6 million) that Branson offered, Walsh instead wagered a “knee in the
groin.” These two are not the first CEOs to put money—and dignity—on the line
over a difference in opinion.
