I've actually thought about that before (does that count as insane yet?). And I actually would find it very cool, at least if it was temporary, if it was on a more serious note, though, I probably wouldn't enjoy it as much, but it'd still be kinda interesting to see how long I could survive.
I already have a plan for when it happens as well. Run downstairs, grab the hunting rifle my dad has, run to the store and pack my pockets with as many things as I can find. Dunno if that would work out well, but I'd give it a try.
If a zombie uprising does begin (which it won't), everyone would die very quickly because the zombies will probably do things like spit sharks out of their mouths and dangle hypnotic lures from their heads.
