Nicole: [banging on door] Come on, Larry, let me in. I'm sure we can talk this through.

Larry: No! Every time I so much as look at a Watterson something terrible happens- [screams as something crashes] Okay, I take that back. Seems just talking to a Watterson's enough.

Anais: But don't you think a class action lawsuit is a slight overreaction for repeatedly scaring off your fiancé?

Larry: [opens a small sliding door]: Every time you guys mess something up I have to pay for it out of my own wages. Why else do you think I have so many jobs?

Anais: Hmm, never thought about that before.

Nicole: Look, I'm tired of your attitude mister! I'm coming in there and we're going to shake hands and make up like adults.

Anais: Mom! You can't do that!

Nicole: [starts to lift the door] Yes... [grows muscles and a monstrous voice] I can!

Anais: No, I mean you can't do that because he's got a- [Nicole forces the door open, Anais sighs] restraining order on us...

Nicole lifts a door open with her brute super strength and gaining massive muscles.

Gumball: No, not that, that! [The view changes to show him pointing at the empty coffee table. Demon Nicole spits out Felicity and they rush over to the living room.
