Another thing that keeps the show afloat? Selling out. Producer Joe Davola said, "We want to make our show as good as possible. And the people on the show use products. So why don't we make money for it?" Well said, Joe! And well executed -- "One Tree Hill" is scripted TV's most product placement-ed show.

Finally, "One Tree Hill" has fans because it's not afraid to (pardon the "Degrassi" theft) go there -- our slideshow of the show's top villains might give you a better idea of just how far out "there" is. Bethany Joy Galeotti told EW that when it comes to her character, say, running through a cornfield from an axe-wielding nanny, her feeling is why not? "It's not like people are going to stop watching our show ... At this point, I say, Just do it."

And we say, just watch it!
