Phelps teased his retirement four years ago, but this time he means business, he told Matt Lauer in an exclusive interview.

"I wanted to come back and finish my career how I wanted," he said. "And this was the cherry on top of the cake."

Indeed, Phelps outdid himself this time around — completing his record-breaking career that spanned five Olympic Games with a whopping 23rd gold medal. The 31-year-old swimmer has 28 medals in total.

But fans of Phelps have no reason to worry — he insists he's left Team USA in good hands with the likes of all-star Katie Ledecky. The 19-year-old breakout phenomenon, who broke the world record to win the Women's 800-meter freestyle final, told TODAY that Phelps has been a major inspiration throughout her swimming career, and the duo even posed for a re-creation of their famous autograph photo while in Rio. (Ledecky's autograph might just be the most important thing that Phelps brought home with him).

As for Phelps himself, he's hinted at his plans for the future, telling TODAY that he and Johnson would "love, love, love" a baby sister for Boomer.

"We started off on a perfect note: We got a boy. We got a beautiful, healthy baby boy, and we're looking to continue to grow our family," he said.

For now, we'll have to sit back and wait while enjoying what is possibly Phelps's greatest contribution of all to America: the #PhelpsFace meme.

Thank you, Michael Phelps.
