Let's see, well, I've got a cat with really sharp claws and hates strangers intruding on her territory, I have a heavy, eight year old laptop, (using it now) a newer broken laptop and an even older, bigger laptop. (Both broken ones are sitting on top of each other on the ground at the foot of my bed.) I've got a plastic double barrel shotgun, I could hold it by the barrels and use it as a bludgeon, I've got a lava lamp, could throw it or break it and use it as a shank, got a glass and plastic box I could throw, a hardcover book that is a little over 1000 pages, an un-boxed Xbox from last Christmas. In the kitchen I've got frying pans, knives, a huge fork, (you know, the ones with the two elongated prongs) then, in our dining room I've got a full bookcase which probably has some big books, on the dining table there's a big lamp (like the Florence Nightingale lamp, just bigger) that could do a crap ton of damage.
All in all, I'm pretty prepared.
