We're hoping Phoenix's adopted son Michael Phelps didn't "jump the shark" when he raced a shark during Shark Week on The Discovery Channel, even though he lost. Not even publicity stunts should diminish the swimmer's status as another animal, the GOAT (that's Greatest of All Time) in Olympic history. Phelps made his first U.S. Olympic swim team in 2000 at age 15, and over the next 16 years, he set record after record, accumulating 28 medals: 23 gold, three silver, and two bronze, the most ever by an athlete in any Olympic sport. In the 2008 Olympics, he won eight gold medals, breaking swimmer Mark Spitz's record for the most by an individual athlete in a single Olympics. More impressive, perhaps, was his performance in the 2016 Games in Rio, when he came out of retirement at age 31 to become the oldest swimmer to win a gold medal. But one wasn't enough: He won five golds and a silver in the competition, including his fourth consecutive gold in the 200-meter individual medley. Phelps officially became a Valley resident last year when he purchased a $2.5 million home in Paradise Valley, where he lives with his wife, Nicole Johnson, and son, Boomer. He also was hired as an assistant coach for the Arizona State University swim team. But unless ASU is recruiting sharks, it's not likely to have any swimmers who can outrace their coach.
