Or The Two Towers. I'm not sure. I mean, The Two Towers is really cool, but Return of the King has Pippin singing in it, and that heartbreaking scene where Merry and Pippin has to split up, and then that scene where they reunite again. And it's also got Gollum (whom was really starting to creep me out) dying, and Eowyn, of course, who's totally awesome. So I guess it's gotta go to Return of the King, though I love all three. :)
