Kristi Yamaguchi (b. 1971) is a gold medal-winning figure skater, and was the winner of the sixth season of Dancing with the Stars.
At the 2011 White House Easter Egg Roll, Yamaguchi wrapped up her story session by saying "So basically Poppy wants all of you to know that it is okay to dream big. And to have those dreams and to work hard and no matter what, you know, keep trying just like they said on Sesame Street, keep trying, and trying. And some day maybe your dreams can come true too."
