I don't have a "humorous" picture to post, so my contribution to this thread is worthless, but as an agnostic who listens to "violent" music and watches "violent" movies, let me say that I'd only ever want to shoot another human being with my camera.
(as an aside, the "Unconstitutional" pic is awesome. It's my wallpaper, starting now.)
