Found another easter egg:
An ithorian on Tattoine that spawns after you talk to drix, called "Do you have the time". When you speak to it, it asks, yep you guessed it, "Excuse me, but do you have the time?" You say no, and then he says look out behind you, and a party of Dark Jedi Masters spawn. You kill them, and talk to the ithorian again, a little bar of text appears: "This ithorian is speechless because of what he just witnessed."
And thats it.
