yor plan is terrible, i have been reading all the other plans and your may be humerous but it is just plain illogical. you gota worry about ammo, headshots with a silly 9 and if the world is infected do you think you have enough ammo for 7 bil headshots? thats not counting if animals can be infected.
you get points for ignorance and humor but none for survival

It's funny, and at least you know about the zombies.

But in all honesty, everything cap'n said is true. And you are going to be deeply saddened to hear that just because your "MP-5" is "Illegal", that doesn't change the fact that its a .9mm and won't do jack to squat. (Unless you somehow get perfect headshots every time. I doubt that.)

1. I would edit out illegal. The government would probably track your IP address and find you.
2. How do you plan on killing all of them? It's an apocalypse, for pete's sake.
3. What's the point of having a zombie pet? Maybe a test subject zombie might be more logical.
