Well, the only one I know is the MTV spoof.

I'll tell you how to get it though:
-First, go to the scene selection on the 1st disc of the Extended FOTR DVD.
-Scroll down until you find the real Council of Elrond scene
-Once you have the cursor on the screen, press down once more. You should see a ring appear in the corner.
-Select the ring and enjoy MTV's hilarious parody!
I know there's at least one more, but I can't remember where it was. Sorry.
