That's the lemon.

Also:

When Life Gives you Lemons, Don't make Lemonade, Make Life Take the Lemons BACK.

GET MAD

I don't want your DANG lemons what am I supposed to do with THESE?!

DEMAND TO SEE LIFE'S MANAGER. Make Life RUE the day it decided to 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.

I'm GOING to invent a COMBUSTIBLE LEMON that BURNS YOUR HOUSE DOWN!
