Dick Van Dyke Celebrates His 90th Birthday With a Mary Poppins Flash Mob

Dick Van Dyke had a jolly holiday on Saturday when he celebrated his 90th birthday. The actor, who is known for his role as Bert in the Disney classic Mary Poppins, was at The Grove in LA when a group of performers dressed like chimney sweepers delivered the most epic flash mob, dancing to the film's songs "Chim Chim Cher-ee" and "Supercalifragilisticexpialidocious."

Van Dyke posted the sweet performance on his Twitter, writing, "I am very grateful that at 90 years old, I can still go out and play!! #dvdturns90." The fun continued on Sunday when he headed to Disneyland for yet another celebration, complete with an appearance from Mary Poppins herself.
