Well, I certainly don't intend on killing any of them. I probably wouldn't know where to start.
About the most vicious weapon I could realistically lay my hands on is either the umbrella in the boot of my car (not very fierce at all), perhaps the twirling staff under my stairs, maybe the snowboard (cumbersome but sharp) in my garage, but the back door is shut, so I'd have to move the bins and open the garage door and I suspect that would attract their attention. Perhaps my wok! That thing weighs a freaking ton.
Meanwhile, I've just been to asda. Phew, lucky I didn't get bitten while I was there! haha...
So I'm stocked up, and my doors are locked.
Short of that, I've got new rock boots by the front door (metal panels ftw) which I can use to kick what little living shit they may have left in them.

Short term prospects? Good...
More than a couple of weeks? I think I'd get so bored, I'd fashion a weapon out of a table leg or somehting and go out and woop some ass.
