Sarah Palin says David Letterman owes an apology to young women across the country for his joke about her daughter. The Alaska governor appeared on NBC's "Today" show Friday, continuing a feud with the CBS "Late Show" funnyman over his joke earlier this week that Palin's daughter got "knocked up" by New York Yankee third baseman Alex Rodriguez during their recent trip to New York. Letterman said it was meant for Palin's 18-year-old daughter, not the 14-year-old who was at the Yankee's game...and that is supposed to make it ok? Not so sure I would want to piss off that gun toten momma!
