The house at Pooh Corner

by A. A. Milne

"I'll show you," said Tigger bravely, "and you can sit on my back and watch me." For of all the things which he had said Tiggers could do, the only one he felt really certain about suddenly was climbing trees.

"Oo, Tigger, oo, Tigger, oo, Tigger!" squeaked Roo excitedly.

So he sat on Tigger's back and up they went.

And for the first ten feet Tigger said happily to himself, "Up we go!"

And for the next ten feet he said:

"I always said Tiggers could climb trees."

And for the next ten feet he said:

"Not that it's easy, mind you."

And for the next ten feet he said:

"Of course, there's the coming-down too. Backwards."
