Papa: What do you want to read tonight?
Caitlin: The big testament.
Papa: Er there is no big testament. Only the new and old testaments.
Caitlin: There is!! The big testament.
(Caitlin has the book open at the contents page).
On another occasion:
Ellie: The food goes down this way, into the small testament, then big testament.
(What Ellie really means is intestine)
