SOCKFULLOFSNAKES. For those who have easier access to snakes than quarters, which is most of us.
SCORPIONARROW. If the arrow doesn't kill 'em the scorpion will finish the job. Scorpion itself may die on impact, this weapon has not been tested.
RAILWAYSPIKEBOARD. A hobo classic. Not very creative but get's the job done. Super handy for when your "buddy", Scuddletooth McGoo, drinks all the shine and won't give back the harmonica.
