Confusion of the Numbers Kind

Ok. So, I've been thinking.  You know how the definition of a prime number is any integer whose only factors are one and itself?  Then, if you think about it, the only number that could be prime is negative one.  All the other integers have at least two positive factors and two negative factors.  Unless you count positive one, which only has one factor.  Whereas, the only factors of negative one are one and negative one.  Even zero can't be a prime number, because any integer from infinity to negative infinity could be a factor, as long as you multiply it by zero.  Makes you think, doesn't it.
  You're probably wondering what this has to do with zombies.  Well, nothing.  It has nothing to do with zombies.  See, the problem with being an unproductive zombie society is that not a lot happens that's worth mentioning.  We don't do much.  And with zombies, that's generally thought of as a good thing.  It means we're not out terrorizing the world and eating brains.  Therefore, you'll see a lot of random posts like this one that have very little to do with zombies.  However, I think it should count that these are the thoughts (and occasionally conversations) of a zombie in the unproductive zombie society.  Keep that in mind as you read the blog.
