Michelle Presents Letterman's Top 10

Michelle Obama's media blitz continued last night on David Letterman's Late Show, where she presented the night's Top 10 list, "Fun Facts About Gardening." The list included No. 7: "In his lifetime, the average American will eat half a radish," No. 4: "If you have an actual green thumb, it might be scurvy," and No. 1: "With enough care and effort, you can grow your own Barack-oli"—at which point the first lady held up a broccoli head carved into a likeness of her husband. The appearance was aimed at promoting her new book, American Grown: The Story of the White House Kitchen Garden and Gardens Across America, notes CBS. (More Michelle Obama stories.)
