After taking an ungodly amount of crap from a Jerkass burger joint manager, Earl thinks about punching him, but thinks better of it...then decides why not, and socks him anyway. That one punch leads to the managers wife discovering his mistress, throwing him out, and finding out he's been stealing from the restaurant. He winds up in jail. And he's apparently the bottom to his big cellmate.
Joy, doped up on happy pills and in the most chipper voice you can imagine, marching over to the obnoxious neighbors who hit Earl Jr. with a beer can, and explaining they have a few days to pack up and move. Or she's gonna return when the happy pills wear off, and thrash them in a very unpleasant manner. They wisely listen to her.
