How much would i get fined for "brandishing my sword" at oncoming traffic?

I would go into the street one warm sunny afternoon and wave it until the cops are called. I think this would be hilarious. serious answers only unless your trying to be a comedian that is acceptable also, id like to know how much id be getting fined and if id have to do any community service. also i am a minor so take that into consideration. and for you slow people, my "sword" is my penis. thank you.
