George Foreman - George Foreman Grill
The former heavyweight boxing champion was approached by company Salton, Inc. to promote their fat-reducing grill in the early 1990s after wrestler Hulk Hogan reportedly turned them down. More than 100 million units have been sold since it was first launched.
Foreman has never confirmed exactly how much he has earned from the endorsement, however he was paid US$137 million by Salton, Inc in 1999 in order to buy out the right to use his name. Before the payout he was paid 40 percent of profits from each grill sold, meaning he was getting at times around $4.5m a month. Overall he's estimated to earn more than $200m from his endorsement of the George Foreman Grill.
Michael Jordan - Air Jordan

After making US$90 million from his playing career, Jordan has been able to make a further billion dollars through investments and endorsements.

Ben Johnson - Cheetah Power Surge
Canadian sprint Ben Johnson is trading on his disgraced past, endorsing a sports drink called Cheetah in a TV commercial.
Johnson was stripped of his Olympic gold medal and world record in the 100 meters at the 1988 Seoul Games after testing positive for steroids. After a two-year suspension, he received a lifetime ban in 1993 for a second positive drug test.
One ad is a mock interview between Johnson and Frank D'Angelo, the president and chief executive of D'Angelo Brands, which makes the drink.

Unfortunately, the pair split in 2015 as Kardashian filed for divorce from Odom and legal restoration of her name.
Rafael Palmeiro - Viagra
During his 19-year career, former professional baseball player Rafael Palmeiro had run-ins with performance enhancing drugs, testing positive for anabolic steroids in 2005.

Palmeiro also appeared on a graphic for the medication that states "I take batting practice", "I take infield practice" and finally "I take Viagra, let's just say it works for me".
