Probably one of the best cartoons of the 70's.
My son who is now 9 loves it too.
Hong Kong Phooey, a somewhat inept super-hero and a master of kung fu and marital arts is always on alert for crime. He gets tip-offs from the police station where he works as Penrod "Penry" Pooch, the mild mannered janitor. Whenever Penry overhears a call for help he quickly dives into a filing cabinet and changes into his karate outfit and then hops into his Phooeymobile. Despite his fallings, and thanks to Spot, his cat, Hong Kong Phooey always manages to save the day.
