Shawn: Goodbye, Michael. We will leave you with one of Bad Janet's classic farts. The smell will linger for 10 million years.
Bad Janet: All right, here comes the boom! Oh wait, actually, before I absolutely let it rip, I just have one more thing I have to do.
Shawn: What?
[Janet grabs Shawn by the neck and throws him against the wall]
Janet: It's me, Good Janet.
Michael: Janet. I thought you were a marble.
Janet: That was a trick. I realized if we wanted our friends to have any chance of survival, I had to learn how to do a lot of bad things really quickly. So, I did. Now I'm ready to go back to being nice again.
Shawn: What happened? [Janet kicks him up against the wall]
Janet: Okay, now I'll be nice again.
