Dick Van Dyke proves age is just a number by continuing to astound everyone with his energy and enthusiasm. At 90 years old, the entertainer proved last weekend he's still got it by leading a sing-along to "Let's Go Fly a Kite" from the film Mary Poppins.

The moment was captured on Facebook by Nicolas DeGrazia and first reported by the TODAY show. 

Not only does Van Dyke still have the vocal chops, he still has a sense of humor too.

"So this just happened," said DeGrazia, "He marches out on the steps of Walt Disney's birthplace on N. Tripp [Avenue] in Chicago and says 'Hi! I'm what's left of Dick Van Dyke!' Then he busts out laughing."

DeGrazia added, "The guy is 90 years old and running around and skipping with a huge smile on his face."

Van Dyke was in Chicago to promote the childhood home of Walt Disney, which is undergoing extensive restorations and will soon be open to the public. The Walt Disney Company recognizes the actor as a "Disney Legend."

This isn't the only instance that proves Van Dyke has more energy than men half his age. Back in February, he appeared in primetime on the program The Wonderful World of Disney: Disneyland 60th, celebrating the 60th anniversary of Disneyland in Anaheim, California. The entertainer sang and danced to the song "Step in Time" from Mary Poppins just as flawlessly as he did 50 years earlier.

We seriously hope we have that much energy when we're 90. Thanks for the inspiration, Dick Van Dyke!
