Jump Drive N' Whale
Hitchhiker's Guide to the Galaxy by Douglas Adams
As if I'd pass up the change to draw an airborne whale.
I'll first start off with the title of this particular entry. I think it's a play on the song "Jump, Jive N' Wail," by The Brian Setzer Orchestra. The whale pun is obvious, but NOT so obvious is the allusion to warp speed motors, also known sometimes as "jump drives." In reference to a hyper jump, or warp drive, etc. But maybe I'm just trying to hard / not trying hard enough.
Alright, so in the booksketch entry before I mentioned a missile being turned into a whale. That obviously wasn't the entirety of the scene. Another missile was turned into a pot of petunias. Very high in the sky.
Does that explain it? No?
Well, our rag-tag bunch of protagonists had just located this mythical planet, when its defense system sprang to life and launched missiles at them. Guided missiles, at that. Well, their target was none other than the Heart of Gold spacecraft that one of the main characters happened to steal. What's so special about this ship? It runs on an "Improbability Drive."
So, in other words, the harder you crank the engine, the more...improbable things become. For example, a pair of guided missiles turning into seemingly random objects/creatures seems highly unlikely right? Even downright improbable. Luckily, the engine was randomly turned on to a high improbability factor (the main character, Arthur saw this as their only means of escape).
SO, I hope that explains it. And I hope it inspires you to read the book (if you have not already). It is pretty probable that you'll enjoy it!
