Eernie should have reprogrammed Judy!
SPOILER ALERT!
When Judy was blackmailing Eernie to tell Agent Kira and Agent Craig about KC's bad doings, Eernie should have just reprogrammed her and erased her memory of all that. She's a robot and he's a computer programmer, so he could do that. Much better than allowing some douchebag to black mail you for something that YOU didn't even do.
