I smell cheeze.

What a wonderous thread this is! Just thinking about some of the lines people have mentioned makes me laugh uncontrolably.
There really are tons of cheezy lines thrown about the movies. Practically everything Legolas says. And then Aragorn gets a few in there. Like in TTT when they first go into Fangorn and Legolas says the White Wizard is near and Aragorn says "Do not let him speak, he will cast a spell on us" (or something like that) well duh future king! What else would a wizard do?
"They have a cave troll." And look they brought tupperware too!
But one of the cheesiest things in ROTK gets me laughing every time. When Frodo wakes up and sees Gandalf and then he has that laugh! Then as the people come into his room he says their name (with the exception of the hobbits) but not Legolas. Legolas comes in and Frodo just kinda smiles, but says nothing. It's like "Hey you, blond guy..."
My final cheestastic thing is Arwen. When she's trying to get Elrond to reforge the sword and she is holding that book and it just slips from her fingers. No offense to anyone who finds that a worthy scene, but is that what happens when you give away your immortal life? You lose the ability to hold onto to anything?
