Nearly three decades passed between the release of The Karate Kid Part III and the premiere of Cobra Kai, but for Ralph Macchio, Daniel LaRusso has never gone away. In his new memoir Waxing On: The Karate Kid and Me (out Oct. 18), the actor looks back on his journey as the titular Kid, which began back in 1983 when he got invited to audition for a movie about a bullied teenager who uses martial arts to defend himself.
