The first weapon is something realistic. It has to be something in your household and that can be quick to get a hold of. Garage, yard or shed are also included in terms of what a "household" is. So what is it?
The second is your choice. It can be anything from L4D's chainsaw to Shaun's paddle or even the Chicago Typewriter from RE4. Whatever.
My realistic household weapon would have to be a heavy wrench from my basement or metal bat or shovel in the garage. Man I don't have anything good.
My weapon of choice would be a Lancer from Gears of War or the gnasher.
