From Winnie-the-Pooh and The House at Pooh Corner, by A.A. Milne
"There's just one thing," said Piglet, fidgeting a bit. "I was talking to Christopher Robin, and he said that a Kanga was Generally Regarded as One of the Fiercer Animals. I am not frightened of Fierce Animals in the ordinary way, but it is well known that if One of the Fiercer Animals is Deprived of Its Young, it becomes as fierce as Two of the Fiercer Animals. In which case `_Aha!_' is perhaps a _foolish_ thing to say." -- the fears of a Very Small Animal Winnie-the-Pooh, p. 84
