There's the story about the man working the night desk at the FBI office. 
They got a lot of wrong numbers, because it was similar to the pizza 
joint.
One night he answered "FBI." When the caller hesitated, he said "You meant 
to call Dominoes ..." The caller exclaimed "Wow, you guys really DO know 
everything!" 

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 the consent of
the King and the King gave them placard that they hung on
their door while they were having sex.
The placard had F. U. C. K. on it
(Fornication Under Consent of the King).

In Santa Cruz, Bolivia, it is illegal for a man to have sex with a woman 
and her daughter at the same time. (I presume this was a big enough 
problem that they had to pass this law?)
