Michelle Obama does Top 10 list

 Mrs. Obama’s list was related to her new book, “American Grown: The Story of the White House Kitchen Garden and Gardens Across America.” The first lady last appeared on the Letterman late night show in March. She has been making the rounds of other talk shows in recent weeks to promote her book. Mrs. Obama’s turn in the spotlight comes as President Barack Obama’s campaign seeks to use his wife’s popularity to help him get re-elected.

The full list of Mrs. Obama’s “fun facts”: Gardening was invented in 1822 by Albert Gardener; plant avocadoes, tomatoes, onions and cilantro together and grow a guacamole tree; eggplants were originally cultivated for use as doorstops; the average American will eat half a radish in his lifetime; the largest zucchini ever grown contained a Starbucks; later this year the Supreme Court will finally rule on “tomato” vs. “tomahto;” if you have an actual green thumb, it might be scurvy; lettuce is 96 percent water and 4 percent lettuce; and the White House tool shed contains shovels, trowels and Weed Whacker One.
