Zombie apocalypse.  Got my guns, my food, my fortress, what else do I need, right?  Uh oh:  No.  Freakin’.  Toilet paper.  I’ve held it for days and I’m running through my house desperately, feeling like I have ten pounds of pudding inside me.  My eReader drops open to Echo and flashes with magic light.  Suddenly  a mountain of Charmin ultra-soft 2 ply appears.  (Angelic choir)  Salvation!
