I think this sign may have been misinterpreted. It appears that it might mean 'Do not urinate between the giant scissors blades while wearing skintight overalls that display your prominent buttocks.' Or something like that.
Don't go fishing with a dotted line? Don't try to pee between the scissor blades? Don't have 1950s-style hair? Don't play games or we'll cut your jump-rope?
