Character from Portal2 game by valve, the quote in full:

“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! I’m gonna get my engineers to invent a combustible lemon that burns your house down!”
