Caroline's audio is named the same as Cave Johnson's files, and I assume the uploaded just grabbed all the files without listening and stuck them in a video.
"Alright, I've been thinking... When life gives you lemons, don't make lemonade! Make life! Take the lemons BACK! *GET MAD!!!!* I DON'T WANT YOUR DAMN LEMONS WHAT AM I SUPPOSED TO DO WITH THESE!?!?!? DEMAND TO SEE LIFE'S MANAGER!!! MAKE LIFE, RULE THE DAY AND THOUGHT HE COULD GIVE CAVE JOHNSON LEMONS!!! DO YOU KNOW WHO I AM!?!?!?!? I'M THE MAN WHO'S GONNA *BURN* YOUR HOUSE DOWN!!!!!! WITH THE LEMONS!!!!!! I'M GONNA GET MY ENGINEERS TO INVENT A COMBUSTABLE LEMON *THAT* *BURNS* *YOUR* *HOUSE* *DOWN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!*" - Cave Johnson, Portal 2
Originally, that audio was going to be part of an audio recording that you would hear like the other ones in game in which Caroline was *Spoilers, but you shouldn't be here if you don't want any* going to be put inside GLaDOS. However, Cave Johnson's voice actor refused to act out his lines for the scene as he found it disturbing, as it sounded "wrong"...Valve agreed and yanked it out of the game. The Caroline lines where she talks about her discomfort are all that remain.
@capitol5000TV Actually, they recorded Caroline's part of that recording, where she becomes GLaDOS, but J.K. Simmons thought the scene was too disturbing for him to record. So they cut it.
"Ive been thinking , when life gives you lemons Dont make lemonade what give the lemons back what am i supposed to do with thease i dont want your [Senseored] lemons get mad do you know who i am im the man whos gonna burn your house down with the lemons im going to get my enginers to create a combustble lemon *cough* *cough*
@JHFunny1000 no the control group didn't tell him that he wasn't supposed to talk about the control group so he was informed he wasn't supposed to talk about them.
“When life gives you lemons, don’t make lemonade. Make life take the lemons back! Get mad! I don’t want your damn lemons, what the hell am I supposed to do with these? Demand to see life’s manager! Make life rue the day it thought it could give Cave Johnson lemons! Do you know who I am? I’m the man who’s gonna burn your house down! With the lemons! I’m gonna get my engineers to invent a combustible lemon that burns your house down!”
You might be asking yourself "Cave, just how difficult are these tests? What was in that phone book of a contract I signed? Am I in danger?" Let me answer those questions with a question. Who wants to make $60 dollars. Cash.
Hum. If someone tells you to say something, and you said "Something." that would be the same kind of thing. He told her to say "Goodbye Caroline." So she said "Goodbye, Caroline!" I don't know if that helped. XD
That's wierd. The game has a quite a bit of cut content. There was also a cut character called "Mel", who was going to be your pal in Co-op mode along with Chell before Atlas and P-Body stepped in. Another scene that exists only in text that suggests you were going to actually FIND Cave Johnson at one point in a computer, and you had to kill him to progress (In fact, he wanted you to).
