Palin did though lash out at Letterman, who she engaged in a very public spat with in June after the late night host joked that Palin’s daughter was “knocked up by [Yankees’ third baseman] Alex Rodriguez.”

Shown a clip of Letterman’s recent “Top Ten” segment listing “things more fun than reading the Sarah Palin memoir,” the former governor shrugged and said “those aren’t even funny.”

Asked if she would ever appear on Letterman’s show, Palin said, “I don’t think that I’d want to boost his ratings.”
