Plot

The cold open features several attempts by Onota (Boboy Garovillo), a member of the Japanese yakuza, to smuggle contraband into the Philippines. In 1964, he arrives at Manila International Airport but is denied entry into the Philippines after customs discovers that he is smuggling diamonds hidden inside a Japanese doll. Five years later, Onota, disguised as a hippie, attempts to smuggle money hidden in his guitar but is caught once again. In 1976, another failed attempt sees Onota disguised as a kimono-wearing Japanese woman who is caught smuggling opium inside his kimono sash.
