The 10-Year Challenge is taking social media by storm, and of course Team USA athletes couldn't miss their chance to participate in the new viral sensation.
Olympic gold medalists Shawn Johnson and Dwyane Wade shared side-by-side photos of themselves, while Paralympic legend Tatyana McFadden showed how her life and sport has changed over the years.
And, though she may have cheated, we can't forget about that adorable photo of 6-year-old Chloe Kim.
Check out a few of the most memorable throwback photos from Team USA...
