Finally I have a wallpaper to offer up! This just screamed “WALLPAPER!”, so here you go.
It’s 1440×900(widescreen), as close to the original artwork’s size as possible.

Don’t mess with Kenny’s girlfriend!

How to use(in Internet Explorer or Firefox): Click the image above, right-click the resulting HUGE image, choose “Set as Background”.

UPDATE: I now have a “Wallpaper” page listed at the top of the page! I hope to eventually change it to “Extras” once I have more than just a wallpaper. I don’t currently plan on putting wallpapers behind a donation wall(a popular practice), but I will encourage people to donate if they like a paper.
