Cave Johnson: Alright, I've been thinking, when life gives you lemons, don't make lemonade!
Cave Johnson: Make life, take the lemons back!
Cave Johnson: Get mad!
Cave Johnson: I don't want your damn lemons! What am I suppose to do with these?!
GLaDOS: Yeah, take the lemons...
Cave Johnson: Demand to see life's manager!
Cave Johnson: 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 going to burn your house down! With the lemons!
GLaDOS: Oh, I like this guy
Cave Johnson: I'm going to get my engineers to invent a conbustable lemon that burns your house down!
GLaDOS: BURN HIS HOUSE DOWN!!!! Burning people, he says what we're all thinking!
