Americans love to take the high and mighty down a notch or two. This video features American presidents being all too human. Sometimes everyone does something clumsy, but when you're the "leader of the free world," you have news media from all over the world on the spot to record the moment for posterity -- and videos like this. Hosted by Michael Jerrick and Lorna Anozie, this Time-Life program contains not-so-great moments that threatened national security, or at least, national dignity. See presidents Ford, Reagan, Bush, and Clinton trip and blunder. With special guest footage from Boris Yeltsin and Dan Quayle.
