One Tree Hill

There is only one Tree Hill, but there are nine(!) seasons of 'One Tree Hill,' the CW's little teen soap that could. In our latest episode, Allison and Kate talk about the humble beginnings of the quietest hit on TV — and the tumultuous behind-the-scenes drama that was revealed years later. Find out everything that went down on set, along with plenty of fun facts about the series. Plus, our hosts look back at their own high school existences, when Kate tried to fix her high school superlatives, and Allison was named "Most Unforgettable."
