T-Bird: "I have fairies in my body. Lots of them. Mo-om! Don't look at me like that - you know what fairies are! They're those things that fly. Well, I have lots of them! And they're in my body. And there's a whole lot that help get rid of all the rubbish in my body with my poo."

AirBear: "Well, God makes my body work."

Silence.

AirBear: "But sometimes it's a little mouse."
