While not actually originating from one of our conversations, this does seem very close. I like the idea of pitting fictional characters against one another. Sadly, most people stick with obvious targets like Freddy vs Jason. I prefer to think of cereal mascots like Tony the Tiger or Lucky the Leprechaun from Lucky Charms battling. A small does of Calvin and Hobbes never hurt anything, really.
JIMMY: Hobbes the imaginary tiger or Hobbes the philosopher?
RICK: Umm, the tiger.
JIMMY: Tony then, because he's grrrrreat!
RICK: What if it were the philosopher?
JIMMY: Tony would maul him to death. Men may be equal, but he's no match for a tiger.
