A number of famous people appeared with secrets, including Col. Harland Sanders who founded Kentucky Fried Chicken ("I started my restaurant with my first Social Security check"), Philo T. Farnsworth ("I invented electronic television"), Pete Best ("I used to be one of THE BEATLES"), and an elderly man, Samuel Seymour, who was the last surviving eyewitness to Abraham Lincoln's assassination (he was 5 years old at the time).
