37. George Foreman
George Foreman is a professional boxing legend. He won an Olympic gold medal and has been called the eighth greatest heavyweight boxer of all time by the International Boxing Research Organization. After he quit boxing, he became a household name for a very different reason, grilling!
Foreman started promoting the George Foreman Lean Mean Fat-Reducing Grilling Machine which has to date sold over 100 million units. The appliance maker reportedly wanted Foreman to be the promoter due to his healthy eating habits. The grills are so popular it is estimated that Foreman has made around $200 million from the endorsement.
