John Stamos -- Wannabe Beach Boy

John Stamos is no stranger to playing with the Beach Boys and once again jumped on stage with some former members, who now perform as Papa Doo Run Run, at Disneyland on Wednesday.

The ageless former "Full House" star -- who is producing a movie musical about the Beach Boys -- played guitar, drums, bongos and sang with the band.

Eat your heart out, Jesse and the Rippers.
