This episode features a callback when Earl and Randy visit Joy in prison from season one when the woman says to Randy "my man isn't here, you wanna chat" and it's the exact same thing a prisoner said to him when they go to visit Hank.
It is revealed in this episode that Joy has a scar on her stomach from when her prom date stabbed her.
This is the first episode in which Earl doesn't try to cross anything off the list.
