How does OReilly calculate the animal that appears on the cover of their "animal" books.
Everybody knows the famous OReilly books use animals and supposedly from my reading the formula to select an animal for a topic is a secret that only Tim and two others know of.

I am interested if anyone has discovered or perhaps figured out how they select what animal for what book. Is there a general purpose set of rules that sort of works and is pretty much correct for several or all their books.

Too keep this fun perhaps include in your answers why a certain animal was picked for a certain topic.
