Wont start..like i have NO battery

Well, the horn never worked..so that out..LOL. Im gonna pull the battery tomorrow if its not raining and take it to autozone and have them test it. Since thats the easiest thing. What do you suggest i use to "jumper" the starter. I think i remember my dad using a wood handle screw driver when i was a little kid on an old ford truck...but he always looked scared trying to do it.
