I've spent an unreasonable amount of thought on the line Janet sings in Rocky Horror: "His lust is so sincere". Now, on the surface, that's a big "DUH!" because that's the nature of lust. But wait: Brad has earlier sung about how hot he is for her, and it's pretty clear he's just being conventional. Brad's lust is not sincere.
Now, I could swill green mead and gnaw raw meat with sincere lust. As for kimchee and lutefisk, well, those would be just for effect. And if I'm just going for effect, I might as well wear a tie. And pants.
