Well, exactly, which is why I see a limited shelf life for this kind of thing. Remember when the success of Teenage Mutant Ninja Turtles was followed by a dozen or so indie titles that copied the adjective-adjective-martial art-animal formula (Middle Aged Radioactive Samurai Hamsters, etc)? It's kind of like that. By the time we get to Lord Jim vs Cthulhu or Warren Harding: Reanimator, the joke will have run its course, if it hasn't already.
