QUIZ: How well do you remember the first episode of One Tree Hill?

It's been almost 16 years since the first episode of One Tree Hill aired.

We know, we can't quite believe it either.

The drama ran for a staggering nine seasons, which saw some of our favourite (and less favourite) Tree Hill residents go through...well, just about everything imaginable.

Including the time that a dog ate Dan's would-be transplant heart. We know it was from one of the much later, kinda OTT episodes, but still. Pretty unforgettable.

And while the series was well known for the dramatic cliffhangers, which usually left one (or more) of the residents in some kind of limbo - but it's also got one of our favourite pilots of any teen drama just about ever.

It brought us into the world of Lucas, Nathan, Hayley, Peyton and Brooke - as well as the rest of the One Tree Hill characters we soon grew to love.

But how well do you remember what actually went on in our intro to Tree Hill? Do you recall which one of the characters didn't actually make an appearance until later on?

Or what about who said the first words of the entire series? Or the last of the pilot episode?

It's time to put your One Tree Hill knowledge to the ultimate test.
