RANDOM FACT
In ancient England a person could not have sex unless you had consent of the King (unless you were in the Royal Family). When anyone wanted to have a baby, they got consent of the King, the King gave them a placard that they hung on their door while they were having sex. The placard had F.U.C.K. (Fornication Under Consent of the King) on it.
Now you know where that word came from.
I was told this, gosh eight years or so ago, while working at Wockenfuss (best candy store ever, btw).
