Simba: Mummy, Jasmine wants to come in.
Mummy: I bet she doesn't!
Simba: She does, look, she is waiting at the door.
Mummy: She's playing "knock down ginger".
Simba: Why does she want to knock me down???
Mummy: No, she doesn't want to knock you down, it's a game naughty children used to play many years ago. You knock on someone's door, then run away when they open it.
Simba: She's not very good at it is she?
Mummy: Trouble is, she can keep this lark up all day long!
