Unfortunately for Douvier, his first attempt at bombing him fails; and the subsequent attempt by Chinese martial artist 'Mr. Chong' (an uncredited appearance by the founder of American Kenpo, Ed Parker) is thwarted when Clouseau successfully fights him off, believing him to be his (Clouseau's) valet Cato (Burt Kwouk) who has orders to keep his employer alert with random attacks.
