Dick Van Dyke is celebrating his 90th birthday the only way he knows with a flash mob performance and singalong.
A group dressed as chimney sweeps, like his "Mary Poppins" character Bert, performed a choreographed dance to "Supercalifragilisticexpialidocious" at The Grove on Saturday.
The actor then joined the group to sing "Let's Go Fly a Kite" as they held up happy birthday signs. The event was organized in part by his wife, Arlene Silver.
He officially turns 90 on Sunday.
