The first viral challenge of 2019 requires a trip back to 2009 to what a difference a decade makes. And in the case of the TODAY anchors, it's not much.
With social media being flooded with photos of people comparing what they looked like in 2009 to what they look like now in the #10YearChallenge, the TODAY anchors decided to get in on the fun.
"Savannah, look at you!" Carson said. "You look better. Hoda, you look great in both. Al, sharp as ever. Craig, amazing.
"And look at me - rounder. What the heck is going on? Who are you people?"
While their looks may not have changed much, it's been a big decade of changes for many of the TODAY anchors.
Savannah, Hoda, Craig and Carson have all become first-time parents in the last 10 years, while Al has watched his kids grow into adults. So much for the notion that the highs and lows of raising children will prematurely age you.
Then there's Jimmy Kimmel, who had some fun with his look back to 2009.
And for others like Bindi and Robert Irwin, the children of the late "Crocodile Hunter" Steve Irwin, it's been a decade of growing into adults.
See everyone in 2029!
