"Final Tally" is the first story in the first issue of Out of the Gutter. It's a great way to start because it's one of those stories that shouldn't be funny at all, but it is.
The narrator is a guy named Shelby, and something snaps in his head. As a result, he knows when people need to be killed for their rudeness or whatever else bothers him. Killing people turns out to be easier than you'd think, and he runs up an impressive total. Then his girlfriend has a problem that Shelby, of course, knows how to solve. What happens after that is even better than what goes before. Check it out.
