Dr. Doolittle and Dr. Gronsfeld were at a local java joint, enjoying a cup of joe (cuppa tea in the case of Dr. D), and making up for having not seen each other in a while.
Dr. G: "It has been way too long, old friend, since we have met. How are you doing? And how is that strange animal of yours, the PushmePullyou, doing?"
Dr. D: "Yes, old chap, way too long. I am doing just fine. Life for me is very interesting. However, life for the PushmePullyou is quite confusing, as he keeps trying to go in 1298 ways at once. I hear you have a new hobby. Please explain."
Dr. G: "My new hobby is called geocaching. It is a modern day high-tech hide and seek game. But, for me, the most interesting part of the hobby is that lots of the caches have puzzles one must solve to find the final coordinates. For example, try out the cipher below."
