I ended up thinking about situations in where poor imagination shows up in writing and the first thing I thought about were the Green Lanterns. I know relatively little about the lore of the Green Lanterns, and I thought up of this joke on a whim.

Out of curiosity I decided to look at clips of the Green Lantern movie. Turns out the first use of his ring: Big fist. Final blow against the bad guy of the movie? Big fist.

If I had the energy to drag out this joke I would have had the next scene having the generic fox green lantern being sliced in half by an imagined up giant mech, or blown away by the death star.

Other things that get a note for use of poor imagination: Anything that deals with dreaming.
