If a zombie were coming at you right now!...what's the best thing within arms reach to defend yourself?
Do you think you can survive?
I reckon that if I clobbered a Zombie with this Lava lamp , they're going down.
No zombie is going to get near enough to do me any damage. My dog will defend me. She usually sits nearby when I'm on the computer and I've never yet seen a zombie that could get past her.
If she wasn't there, of course, I'd staple their feet to the floor with my stapler (like Lisbeth Salander did to the bad guy in The Girl Who Kicked the Hornet's Nest.
I would reach for any sharp or heavy object. But I prefer to run as fast as I can.
