The #10YearChallenge took over social media this week. As is always the case with internet trends, what at first emerged as a way for netizens to share how they've changed over the past ten years has been picked up by politicians, activists and celebrities alike.
A host of people have posted photos of themselves, showing a striking difference over the 10-year period, but for some, there has not been much change.
Israeli Prime Minister Benjamin Netanyahu was not among the skeptics: he posted a photo of a barrier Israel put up on its border with Egypt.
"That's [the] real challenge we are facing," wrote a user going by nickname Numan Aziz, referring to the almost decade-long civil war in Syria, "Muslims, follow the right path instead of following trends".
Politics aside, football star Mesut Ozil jumped on the bandwagon just to remind everyone about the change "we should care about."
He was joined by a slew of activists, who pointed to the decline of coral reefs, rainforests and the environment, in general.
Some people, including pop star Demi Lovato, called on their followers to focus on their real lives instead of trying to impress friends and strangers on social media. Ironically enough, she posted her own photographs on Twitter.
Tongue-in-cheek conspiracy theories have also been popping up, suggesting that the fresh challenge was a plot designed by Facebook founder Zuckerberg.
Incidentally, Caitlyn Jenner, the Olympic-champion-turned-reality-star, has been crowned the ultimate winner of the challenge. A stunning transformation, indeed.
