We live in a time of wonder my friends. Once it was thought that if you dug straight down through the earth you would end up in China, where (it is assumed) you would be able to get some really good Chinese food. Of course we know this to be a myth. The Morlocks would get us long before we reached the Earths inner core of cottage cheese.
But thanks to GPS and advances in baking technology, we can now create The Earth Sandwich!
Thus prooving scientifically that some of our speciese has waaaaaay too much time on their hands.
