easter eggs

I have played a lot of RPGs in my days Zelda, Diablo 2,Dungeon Siege,World of war craft,morrow wind, baulders gate dark allince,and i hate to admite it Runes scape not very long thow. In most of these games there are some cool "easter eggs" to discover, So i was hoping that someone here know of any ways of uncovering anything cool.
already discovers the Brock! Brock! Brock! lanuage setting.

Now that you mention it, there hasn't been mention of any easter eggs in this game. The coolest one I can remember off hand is clicking the little observer unit in Starcraft until you get a transmission from the witch in Diablo 1.
