The God-Force

K-9: Halt!
Thor: What is it now?
K-9: Inquiry: have you read this book, The Labours of Hercules?
Thor: No. Why should I?
K-9: Agatha Christie compared her detective Hercule Poirot to the Roman demigod Hercules. As you're named after a Norse god, I thought you might find her stories about how mortals can overcome great obstacles instructive.
Thor: I resent your implication that I am only named after a god! I wield great power because the god-force lives inside me!! Now walk on, dog, before I smite thee!!!
