Haha , wow that is funny about Yellow Submarine. I do know that the Beatle who wrote it was trying to make it sort of a kids song so he kept the lyrics simple and easy to remember. I used to do cable modem installs across several cities back during the flip phone days. I had a map that had one city on one side and the other city on the back. I wore out several of those. When I was a kid we used to get trip tiks from AAA before we headed out on long trips. I use GPS today, but I still usually look at a map ahead of time so I have a general idea of where I am going.
