Yup, that one with the Welsh and a bow and arrow is something to do with the defence of Chester and the laws about having to practice with a bow and arrow so that there would be people proficient at archery if an army was raised. I think you were only allowed to kill a Welshman with a bow on any day except Sunday or something daft like that.
My personal favourite was a local bylaw at Greenham Common, which you will remember, is where the USAF sited its Tomahawk cruise missiles in the UK, to much protestation from the tree-hugger brigade. Before the site was constructed, there used to be a sign on the common which read: 'The launching of missiles is strictly prohibited' in reference to not being allowed to play ball games and stuff like that.
