What's your deepest secret? In this day and age, a lot of people post all of their secrets on the Internet. I only have one secret that I'm absolutely taking to the grave. Do you know who can keep a secret? Old people. I think they keep all of those secrets in their finished basements, like the basement in the "Deepest Secret" video by On the Frontline. You can check out the video here. Don't keep your love for the video a secret.
