A good bayonette mount always comes in handy. A can of Aquanet, a zippo lighter, some duct tape and a little craft know-how makes a dandy flamethrower. You'll need a silencer and a loudener. An MP3 player to play "Ride of the Valkyries". A webcam with WiFi so you can post pics of self defence shootings on facebook. And then there's the pirahana launcher, gotta have a pirahana launcher.
