" How did you fall in, Eeyore?" asked Rabbit, as he dried him with Piglet's handkerchief.
"I didn't," said Eeyore.
"But how--"
"I was BOUNCED," said Eeyore.
"Oo," said Roo excitedly, "did somebody push you?"
"Somebody BOUNCED me. I was just thinking by the side of the river--thinking, if any of you know what that means--when I received a loud BOUNCE."
"Oh, Eeyore!" said everybody.
"Are you sure you didn't slip?" asked Rabbit wisely.
"Of course I slipped. If you're standing on the slippery bank of a river, and somebody BOUNCES you loudly from behind, you slip. What did you think I did? "
