Oooh what about the cheddar-scene where Aragorn starts speaking Danish to Arwen?

Something like "min älskling", I just crack every time...
And then, of course, there is dear Orli with his
"They're taking the hobbits to Isengard!"
Surprise, surprise. A Mr. Obvious line for real.
"I feel a faint tingling in my fingers, I think it's affecting me!"
Oh please.
