Everyone wants to marry Zoro. Hypothetically. Sanji can’t believe everyone would pick that useless patch of growing mold over him, and considers killing Zoro. Not hypothetically. He has a list on why Zoro would be the Worst Husband Ever, not that he spends a lot of time thinking of a (purely hypothetical!) situation where he is married to Zoro, fuck you very much. (a.k.a, the one where Usopp invented Fuck, Marry, Kill.)
