I used SV_CHEATS 1, and IMPULSE 101 so as to get the rocket launcher and shoot off the eyes. I then waited for GLaDOS to stop her chit-chat and took the eyes to the side to listen to their entire string of sayings. The Orange and Blue eyes are by far the best ones, as the purple one doesn't chat, and the red one just snarls.
This is the Blue eye, I didn't catch it right at the start, but I allowed it to loop some so as to catch it all. I have captions on so you can read it JUST in case you misunderstand something. even though sometimes the voice says things that aren't the exact words in the captions. ((like when you burn the first eye, GLaDOS says "incinerated" while the caption says burned))
