Have you ever wondered why Vash's description was so bizarre? Sure, he was blond, wore red, could be mistaken having a mohawk. But short legs, WTF? So an idea hit me.
Wolfwood shrugging his way out of a nightshirt and getting ready to face the day, i.e. a perfectly valid excuse to draw the muscles in his back. Bow-chikka-wow-wow.
Possibly unintentionally provocative, so a little NSFW.
