Bessie: I made it with milk from my body.
Otis: Food is my enemy!
Bessy: Whew, what a relief!
Otis: Huh. Not what you usually say when your heart is breaking into a million pieces.
Bessy: I didn't know what was worse - having you for a son or being married to a rat.
Otis: Wow, you already packed a bag and everything.
Pip: I keep it handy in case anyone ever destroys my home.
Otis: Wow, you're a fast-thinking rat with a can-do attitude. Come on, roomie.
