ROUGH CUT (NO REPORTER NARRATION)

STORY: U.S. First Lady Michelle Obama appeared on The Late Show with David Letterman Tuesday evening (June 5) to promote her new book, "American Grown: The Story of the White House Kitchen Garden and Gardens Across America."

In classic Letterman fashion, Obama read the "Top Ten" list. Michelle Obama's was titled: "Top Ten Fun Facts About Gardening."

The number one "fun fact"?

"With enough care and effort, you can grow your own 'Barack-oli'," Michelle Obama said, displaying a green broccoli-like growth, which featured a green plastic face resembling her husband, U.S. President Barack Obama.
