Okay, you know that we all imagined this moment in our own heads... Yes, YOU did too... but DUDE:

From The One Ring.net:

Lincoln Center Event:

To end the evening, Peter told one last story about a gag that was played on Viggo Mortenson during filming at Dunharrow. Peter gave Hugo Weaving a pair of Matrix-style glasses, and as Viggo entered the king’s tent to meet with Elrond, Hugo Weaving stood up, removed his cloak, revealed his glasses, and said: "Your Dunedain disguise cannot fool me, Mr. Anderson." Peter called this the "ultimate geek moment."
