We imagine Bert, the one-man band turned artist (turned chimney sweep turned kite salesman) from "Mary Poppins" would be smiling.
Dick Van Dyke, who portrayed the beloved character in the 1964 Disney classic, turned 90 on Sunday.
A flash mob assembled at The Grove, Entertainment Weekly reports, where fans dressed as "Mary Poppins" characters gathered to celebrate with a serenade.
The group performed songs like "Let's Go Fly a Kite" and "Step in Time" for Van Dyke, who was so moved by the gesture that he joined them.
"I am very grateful that at 90 years old, I can still go out and play!!" the star shared on Twitter.
