As I've mentioned before I don't like posting videos without game content. So here's an optional rule Six-Shooters and Wagons based on the video.
Quirky Characters - During character creation you can give your character a weird quirk. This may be a catch phrase you have to shout before going into a fight or the fact the you're a grown man that love dolls (like the younger Henderson brother from the video). This quirk should come into play at least once per session. You may reroll one die per session. If this roll is for a task/save/attack, you must choose to use the reroll before success is determined by the GM.
