Comedic Remorse

(Fox News) - "Late Night" host David Letterman says he has reservations when doing jokes about John McCain's age. Letterman tells Rolling Stone, "Every time we have these jokes about him, I always think to myself, 'This is not entirely fair.'"

Letterman has done plenty of old fogey jokes about the 72-year-old McCain who would be the oldest man elected president to a first term. Letterman once said on his show, "John McCain looks like the kind of guy who brags that his new denture adhesive allows him to eat corn on the cob."

He says McCain's age is an obvious target, and that poking fun at Barack Obama is more difficult. He says, "I don't think people have a way to get in there. There's nothing automatically that you can go to."
