George Foreman Grill

• 100 million grills sold

Boxer George Foreman, two-time world heavyweight champion, got the deal of a lifetime outside of the ring. Although he initially signed on to earn 45 percent of the profits in return for the use of his name, by 1999 the grill had sold more than 100 million units, and the maker of the grill opted to buy out their spokesperson instead. Foreman earned $137.5 million for his endorsement, plus an additional $11 million for grill-related TV appearances. "Big George" tried to parlay that success into other products, including a line of frozen meats, but they've flopped in comparison.
