Nah, just work like a dog, be polite to everyone (holdover from samurai killing anyone they liked), like outdated 70's music and you'll get at least 60%. The schoolgirl underwear sniffing is purely optional.
(apparently the sheeps' eyeballs story arises from a cultural misunderstanding in which the cultural practice was to use the eyeballs to decorate the food as an indication of the freshness of the meat, and they were not for consumption!)
