In the Calvin and Hobbes collection entitled "Weirdos from Another Planet", wait for the Rosalyn series where Calvin doesn't let her in, then tries to mail himself in a cardboard box to Australia. He writes it as TO OS TRYLA. However, in the 3rd panel, it changes to TO OSTRIA, because of there not being a line on the bottem of the L. And then, in the final panel, there is no writing at all! Calvin and his mom are still talking from the same sides of the box. Hmm, just plain weird.
