"Easter (Eggs)? But It's Not Even Christmas?!

Rasputin the Evil Balrog writes: I just wanted to make sure everyone knows that there are two Easter Eggs on the Extended Edition of ROTK. The bogus interview of Elijah Wood conducted by Dominic Monaghan (as German journalist Hans Jensen) that PJ mentioned at the Oscar Party was already confirmed by your earlier report from Britain and is found on the first disc of the film.
On the second disc there is a second Easter Egg, though, that I haven't seen anyone mention. It's this year's MTV Movie Awards skit featuring Vince Vaughan and Ben Stiller taking a meeting with Peter Jackson to pitch their ideas for a sequel to Lord of the Rings ("The Ring was destroyed." "But what if it wasn't?"). Not my fave of the three years of MTV Eggs, but still hilarious.
Oh, and FYI, the Eggs are accessed on each disc by going into the chapter selection menu, choosing the last chapter, then pressing the down arrow on your remote. A Ring icon will appear at the bottom of the screen, and you hit enter to access the egg. Very similar to the previous EEs."
"On New Line Home Entertainment’s extended version of the monumental Peter Jackson epic 'The Lord Of The Rings: The Return Of The King' the studio has added some hidden material, as expected. Here is how to get to these hidden gems.
Insert the first disc of the DVD set and go to 'Select A Scene.' There highlight the very last scene on the disc, entitled 'The Siege Of Gondor.' Press the 'Down' arrow key on your remote control and the One Ring will appear on the screen. Press 'Enter' now and you will be treated to wonderful gem of a high-spirited practical joke played on Elijah Wood by his co-star Dominic Monaghan. This must be the funniest Easter Egg I have ever seen.
Now insert the second disc of the DVD set and once again go to the 'Select A Scene' section. Highlight the menu entry 'Fanclub Credits' and then press the 'Down' arrow key on your remote control and the One Ring will appear. Now press 'Enter' and you will get to see a hilarious MTV Special from the 2004 MTV Awards, featuring Peter Jackson, Ben Stiller and Vince Vaughan.
