The stupidest law that I will never forget is this one revering to an unmarked crossroads.
When 2 cars meet at an intersection, each one shall stop until the other one has gone.
Figure that one out if you can, lol
In Chico, California you can be fined $500 if you detonate a nuclear device within the city limits.
Of course, the question remains to be asked about who will be left alive to issue said fine...
And let's face it. If you can afford your own nuclear weapon, $500 is loose change.
