The Countdown series was a recurring animated segment during the early years of Sesame Street. Each clip began the same: a wide-mouthed launch director (perched atop a podium) stands next to a button, ready to trigger a rocket (proudly displaying the letters "USA" on its side). A group of people closely stand by, awaiting the launch. The director counts backwards, from ten to one, but when he's finished counting, some kind of disaster often occurs. In early episodes, Carol Burnett would appear at the end of one or more of these segments in a filmed tag, where she laments, "Well, back to the ol' drawing board."
