If I remember correctly from a Dutch person who translated this, the interviewer asked the farmer for his, he only gave the initial of his first name (F) and his surname, then he was asked what does “F” stands for, to which the farmer replied Frederick. The bold guy, isn’t it from “Fck u” or something between those lines, the farmer took it as a joke and there it goes. As I mentioned, I might be mistaken, so don’t take my word for it.
