Mark-Paul Gosselaar and Mario Lopez recreated a throwback picture from their time on the 1990s sitcom Saved by the Bell. They were inspired by the viral #10YearChallenge. Their photo was more of a 30-year challenge. Their original snapshot was from 1989. They reunited on Lopez's show Extra to create the moment. Gosselaar currently stars in the new Fox series The Passage. Have you done the challenge yet? Have you gone further than 10 years?
