A man — wondering if an attack on Iran is in the works — wanted to know when America is going to "send an air mail message to Tehran." McCain began his answer by changing the words to a popular Beach Boys song. "Bomb bomb bomb, bomb bomb Iran," he sang to the tune of Barbara Ann.
UPDATE: Here's the video. It's interesting — the clip is a bit less outrageous than the words in cold print. Somehow his inflection makes it seem as if he's clarifying the intent of the questioner rather than advocating a carpet-bombing campaign.
