Nukes launch Chuck Norris at their enemies.

With Chuck Norris, the nukes whistle at him, just to keep on his good side.

It's in his (Mitnick's) autobiography Ghost in the Wires. In his telling of the story they put him in a more restrictive environment exactly because of the reason given (launching nukes by whistling into a phone)

At least Kevin wasn't a sanctimonious hateful bible thumping religious fanatic homophobic bigot like Chuck Norris.
