When I was younger I brainstormed writing a story about an undead cowboy from the wild west, cursed to roam the earth seeking vengeance against a witch who shot him in the back, leaving a wound that literally never heals. (You can probably guess about how old I was and what life event I had recently endured...)
Anyway, he was to be named Sirius Clay, which in his condition would make him "Dead Sirius". Which was of course a play on the term "Dead Serious". Which kind of matches my boring deadpan tone.
Not sure why that came back to mind when I was signing up for this site though...
