Let's Say You've Gone Back In Time

Shotguns and the evil undead have enjoyed a long-standing love affair. Many types of weapons have been popular for taking down such creatures: swords, axes, cricket bats, crossbows, the ever-popular chainsaw. But there is nothing like the power of a shotgun to unleash the destruction required to bring down an ultimate creature of evil. In fact, the two are so entwined that today things like this are not at all uncommon. But what if you find yourself back in time, before the age of modern technology? Well for one, there is this:

This will teach you all you need to know on the non-supernatural realm, as well as guaranteeing you a spot as the greatest person in history. (That is, if you are prepared for the soul-crushing horror when you return to your own time and realize that you have changed history, and that everything and everyone that you knew is no more. But on the bright side, you’ll be really famous.) But if you are being attacked by Lovecraftian horrors from beyond time and space, then what you really need is this t-shirt for inspiration and a gun to back you up.
