GlaDOS: Remember when the platform was sliding into the fire pit and I said "Goodbye" and you were like GlaDOS: [in a deep male voice] "No way!" GlaDOS: [normal voice] And then I was all "We pretended we were going to murder you?" That was great!
Cave Johnson: All right, I've been thinking, when life gives you lemons, don't make lemonade! GLaDOS: Yeah. Cave Johnson: Make life take the lemons back! GLaDOS: Yeah! Cave Johnson: Get Mad! GLaDOS: Yeah! Cave Johnson: I don't want your damn lemons! What am I supposed to do with these? GLaDOS: Yeah, take the lemons! Cave Johnson: 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 whose gonna burn your house down - with the lemons! GLaDOS: Oh, I like this guy. Cave Johnson: I'm gonna get my engineers to invent a combustible lemon that'll burn your house down! GLaDOS: Burn it down! Burning people. He says what we're all thinking.
"Life is like a Lemon. Sour as hell sometimes, but if you aspire to, you can make lemonade." - C. L. D.
