Dick Van Dyke turned 90 on Sunday, but the beloved film and television actor seems ageless.

Need proof? Just take a look at his nostalgic birthday bash, which took a twist after a flash mob performed a medley of his song-and-dance routines from "Mary Poppins."

At first, Van Dyke watches from a balcony overlooking the crowd as they break out into his memorable moves.

"Woo!" he says when it's over. "That's unbelievable."

But what's really unbelievable is that he then goes down to join the mob and onlookers, and even leads them in a "Mary Poppins" sing-along of his own!

Clearly, he's still got all the charm that he brought to the big screen back in 1964 for his role as Poppins' pal Bert.

"I am very grateful that at 90 years old, I can still go out and play!!" he tweeted after the Disneyland event, which took place Saturday.

And for him, that was some fairly restrained play. As anyone who follows his wife, Arlene, on Vine knows, Van Dyke still gets pretty darned playful!
