This retractable roller ball pen features a "special 'gun sight'-shaped clip," a gun-barrel design and a stand that serves as the grip. It's even made by a company called ACME, which seems very appropriate. On the negative side, the pen does run $130, which makes me wonder how Wile E. Coyote could afford all that crap.
