Watson was once again on charmingly-if-mildly-pugnacious form last night talking to David Letterman. When Dave quizzed the actress about her plans to study liberal arts in America and asked her exactly what "liberal arts" involved, Watson responded, "Do you live in the States? Shouldn't you be telling me this?" (Letterman's response: "The kid just gunned me!") Watson also kept her cool when Dave produced a photograph of her "wardrobe malfunction" at the recent, rain-soaked UK premiere of Harry Potter and the Half-Blood Prince ("At least I'm wearing underwear") and admirably coped with the fact that Letterman appears to know even less about the Potter movies than I.
