I'm confuzzled.

The ghost gun reference is related to the 3D printer manufacturing of firearms.

SACRAMENTO -- Angered by Congressional failure last week to address the emerging threat of untraceable and undetectable guns, made possible by manufacturing with three-dimensional printers, Senator Kevin de Leόn (D-Los Angeles) today announced he would introduce legislation to ban the sale, manufacture, purchase and trafficking of “ghost guns” unless they are pre-registered with the Department of Justice through a serial number and gun owner background check. In order to receive a serial number, self-made or assembled firearm must include permanent metal components that cannot be detached and that are detectable as required by existing law.

I think it was his audition tape for Saturday Night Live.
