Surviving the World
A Photocomic Education by Dante Shepherd
Lesson #633 - Space
You'd think this was inspired by Firefly, but it actually came from having finally worked through the fourth Dark Tower book. I leave the Firefly obsessions to some other webcomic-er.
I now hope you go around the rest of the day with the theme from "The Good, The Bad, and The Ugly" stuck in your head.
