DID YOU KNOW?

In ancient England people could not have sex unless they had consent of the king (unless they were in the Royal Family).
When people wanted to have a baby, they had to get the consent of the king, and 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. Hence that's where the word F*ck came from.

My friend has sent me this mail.
Have you heard of this?
Is it true?
