I have zombie bugs in my apartment.
I was writing a few minutes ago, and then noticed some bug with an inch-long body and a ton of legs crawling across my floor. I chased it and smashed it against the side of my couch with a book. Somehow, this resulted in the bug's body sliding to the floor while it's legs were stuck to the couch. AND THE LEGS WERE STILL MOVING! In fact, even a minute later, after I found a tissue and cleaned the body off the floor, the legs were still twitching!
So if you really want to be prepared for the zombie apocalypse, make sure you keep your apartment sealed and spotless.
