Zombies can't swim

If you are not a liberal, buying a boat can help you escape the zombie apocalypse.  Liberals are immune to zombies because zombies eat brains.  This is also why non-leftists need to buy plenty of weapons to defend our tasty brains. 

Remember Liberals, on occasion a genetic singularity occurs and you spawn a non-Liberal. This means your children could have brains and need to be defended. We will defend your children from the zombies. Just buy us a little ammo with your EBT cards ok? Oh, that's spelled E B T.
