I read this in a Rolling Stone article about McCain. Funny.
During his 1992 campaign, at the end of a long day, McCain's wife, Cindy, mussed his receding hair and needled him playfully that he was "getting a little thin up there." McCain reportedly blew his top, cutting his wife down with the kind of language that had gotten him hauled into court as a high schooler: "At least I don't plaster on the makeup like a trollop, you cunt." Even though the incident was witnessed by three reporters, the McCain campaign denies it took place.
On the night he was elected senator in 1986, McCain exploded after discovering that the stage setup for his victory speech was too low; television viewers saw his head bobbing at the bottom of the screen, his chin frequently cropped from view. Enraged, McCain tracked down the young Republican who had set up the podium, prodding the volunteer in the chest while screaming that he was an "incompetent little shit."
(Let’s put nuclear weapons in McCain's hands.)
