her alma mater University of Virginia on May 20, 2012, at Randolph-Macon College on June 1, 2013, and at Princeton University on June 1, 2009. She also works with Carmen Marc Valvo to help publicize the deadliness, yet preventability, of colorectal cancer. On May 16, 2010, Couric received an honorary doctor of science degree for her efforts in raising awareness of colorectal cancer and for her commitment to advancing medical research from Case Western Reserve University, and later gave the university's 2010 convocation keynote address. In 2016, she starred as herself in Sully to recreate the 60 Minutes interview for the film. In 2011, she gave the university commencement speech at Boston University and was awarded another doctoral degree, Doctor of Humane Letters. She has also hosted a Sesame Street special, "When Families Grieve." The special, which aired on PBS on April 14, 2010, dealt with the issues that children go through when a parent dies. On February 6, 2011, Couric guest-starred on the post-Super Bowl episode of Glee, playing herself interviewing Sue Sylvester after the cheerleading team lost the championship. Sylvester sarcastically referred to Couric as "Diane Sawyer" during the segment. Couric is the author of two children's books and a non-fiction collection of essays. Her children's books The Brand New Kid (2000) and The Blue Ribbon Day (2004) were illustrated by Marjorie Priceman and published by Doubleday. The Brand New Kid topped the New York Times best seller list for children's picture books, and was adapted into a 2006 musical by Melanie Marnich and Michael Friedman. Couric's third book, The Best Advice I Ever Got: Lessons from Extraordinary Lives, was published by Random House in 2011. The book is a collection of essays compiled over the past year by Couric; contributors include New York City Mayor Michael Bloomberg, Queen Rania of Jordan, and former Today Show colleague Matt Lauer. Couric said that a 2010 convocation keynote address she gave inspired her to write the book. To this end, all profits of the book will be donated to Scholarship America. In December 2013, Couric ran a segment on the HPV vaccine which critics accused of being too sympathetic to the scientifically unsupported claims that this vaccine was dangerous. For example, Seth Mnookin accused her broadcast of employing false balance. In addition, Alexandra Sifferlin, of Time magazine, compared Couric to Jenny McCarthy, a well-known anti-vaccine celebrity.
