A flash mob serenaded the legendary funnyman by dancing to "Supercalifragilisticexpialidocious" as he watched from a balcony at The Grove in Los Angeles.

He then joined in on the action by singing "Let's Go Fly a Kite" from Mary Poppins smack in the middle of the crowd. The birthday treat was the work of his wife, Arlene Silver.

His 90th birthday falls on Sunday.

He previously said in an interview that his secret to staying young is exercise - as well as candy and ice cream.
