When you don't know where you're going to be, pack some hot dogs! Let's say you've been magically transported into the paleolithic era! You have nothing but sticks, stone tools and a rudimentary knowledge of fire. Well then, roast those wieners al fresco! Now let's say you found your way forward in time, but overshot and ended up in a strange dimension where the only sources of heat were rotating metal rods under sneeze guards. Do your hot dog convenience store style! Boil it! Fry it! Toss it in the oven with some baked beans! Whatever your time and/or dimension, you will never be hungry with a hot dog by your side!
