"13. In England, all men over the age of 14 must carry out two hours of longbow practice a day."
In fact I just finished about an hour ago.
And the reason why we do this:
"7. In Chester, Welshmen are banned from entering the city before sunrise and from staying after sunset."
"6. In the city of York, it is legal to murder a Scotsman within the ancient city walls, but only if he is carrying a bow and arrow."
I quite liked this one:
"23. It is an act of treason to place a postage stamp bearing the British monarch upside down."
I must admit I've been guilty of this but I get round it by writing upside down on the envelope.
