It was, depending on who you ask, the best “Top 10” list on David Letterman has ever seen. A newly slim Britney Spears stripped down to a bikini to deliver the funny rankings on Tuesday night. In a black string bikini and with a flower behind her ear, Britney Spears read a list of “Top 10 Ways the Country Would be Different if Britney Spears Were President.” But it seemed like everyone—including the writers—spent more time focusing on Britney’s appearance than what was coming out of her mouth. Some of the jokes on her list: “Three words: Vice President Diddy.” Another: “Costume changes between press conferences,” and her final jab was, um, a real side-splitter: she wished that “the media would pay attention to me and care about what I’m doing.”
