So you want to be a Crazed Street Preacher? It takes a lot of hard work to be this nuts. You have to really want it!
Wake up at 3:30 am to start your day with a bowl of cold shredded wheat and some hot chastisement. As a crazy street preacher you can't bathe, shave or cut your hair... ever again. So it's out the door and on your way.
You will need something to stand on so that everyone can see you. Soap boxes work well for this, as well as pickle boxes, or bean boxes. Carry your box to a corner that you know will be busy once the sun comes up and stand on top of your box to begin your daily tirade.
Start yelling about a topic of your choice, usually Revelations. Make sure that you pace yourself. You have to do this until at least 12:00 am when you pass our from exhaustion and delusions.
